'''Purple''' is a [[Color|color]] similar in appearance to [[Violet (color)|violet]] light. In the [[RYB color model]] historically used in the arts, purple is a [[Secondary color|secondary color]] created by combining red and blue pigments. In the [[CMYK color model]] used in modern printing, purple is made by combining [[Magenta|magenta]] pigment with either [[Cyan|cyan]] pigment, [[Black|black]] pigment, or both. In the [[RGB color model]] used in computer and television screens, purple is created by [[Additive color|mixing]] red and blue light in order to create colors that appear similar to violet light. According to [[Color theory|color theory]], purple is considered a cool color.<ref>{{Cite web |title=Guide to Warm and Cool Paint Colors {{!}} Benjamin Moore |url=https://www.benjaminmoore.com/en-us/color-overview/color-insights/warm-and-cool-colors |access-date=2025-04-27 |website=www.benjaminmoore.com |language=en-us}}</ref>

Purple has long been associated with royalty, originally because Tyrian purple dye—made from the secretions of sea snails—was extremely expensive in antiquity.<ref>{{Cite news|last=Dunn|first=Casey|url=https://www.nytimes.com/2013/10/09/science/the-color-of-royalty-bestowed-by-science-and-snails.html|title=The Color of Royalty, Bestowed by Science and Snails|date=2013-10-09|work=The New York Times|access-date=2020-04-04|language=en-US|issn=0362-4331}}</ref> Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the [[Place:Byzantine Empire|Byzantine Empire]] and the [[Religion:Holy Roman Empire|Holy Roman Empire]], and later by Roman Catholic [[Religion:Bishop|bishop]]s.

== Etymology and definitions ==
The modern English word ''purple'' comes from the [[Social:Old English|Old English]] ''purpul,'' which derives from [[Social:Latin|Latin]] ''purpura'', which, in turn, derives from the [[Greek language|Greek]] {{lang|grc|πορφύρα}} (''porphura''),<ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dporfu%2Fra πορφύρα] {{Webarchive|url=https://web.archive.org/web/20210307233455/http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dporfu%2Fra |date=2021-03-07 }}, Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus</ref> the name of the [[Tyrian purple]] dye manufactured in classical antiquity from a mucus secreted by the [[Biology:Bolinus brandaris|spiny dye-murex]] snail.<ref name=":1">{{Cite web |title=purple, adj. and n. |url=http://www.oed.com/view/Entry/154956 |access-date=2020-04-04 |website=OED Online}}</ref><ref>{{cite web|title = Online Etymology Dictionary|url = http://www.etymonline.com/index.php?term=purple|website=Etymonline.com}}</ref> The first recorded use of the word ''purple'' dates to the late 900s AD.<ref name=":1" />

{{Main|Tyrian purple}}

Purple first appeared in prehistoric art during the Neolithic era.  The artists of Pech Merle cave and other [[History:Neolithic|Neolithic]] sites in France used sticks of [[Chemistry:Manganese|manganese]] and [[Chemistry:Hematite|hematite]] powder to draw and paint animals and the outlines of their own hands on the walls of their caves. These works have been dated to between 16,000 and 25,000 BC.<ref>Anne Varichon, ''Couleurs-pigments dans les mains des peuples'', p. 144–146</ref>

Purple textiles, dating back to the early second millennium BCE, were found in [[Place:Syria|Syria]], making them the oldest known purple textiles in the world. These findings include textiles from a burial site in Chagar Bazar, dating back to the 18th-16th centuries BCE, as well as preserved textile samples discovered in gypsum at the Royal Palace of [[History:Qatna|Qatna]].<ref>{{Cite journal |last1=James |first1=Matthew A. |last2=Reifarth |first2=Nicole |last3=Mukherjee |first3=Anna J. |last4=Crump |first4=Matthew P. |last5=Gates |first5=Paul J. |last6=Sandor |first6=Peter |last7=Robertson |first7=Francesca |last8=Pfälzner |first8=Peter |last9=Evershed |first9=Richard P. |date=December 2009 |title=High prestige Royal Purple dyed textiles from the Bronze Age royal tomb at Qatna, Syria |url=https://www.cambridge.org/core/journals/antiquity/article/abs/high-prestige-royal-purple-dyed-textiles-from-the-bronze-age-royal-tomb-at-qatna-syria/69EC1A74600EC74AAAC26D2F585ACF5A |journal=Antiquity |language=en |volume=83 |issue=322 |pages=1109–1118 |doi=10.1017/S0003598X00099397 |s2cid=162563421 |issn=0003-598X|url-access=subscription }}</ref><ref>{{Cite journal |last1=Sukenik |first1=Naama |last2=Iluz |first2=David |last3=Amar |first3=Zohar |last4=Varvak |first4=Alexander |last5=Shamir |first5=Orit |last6=Ben-Yosef |first6=Erez |date=2021-01-28 |title=Early evidence of royal purple dyed textile from Timna Valley (Israel) |journal=PLOS ONE |volume=16 |issue=1 |article-number=e0245897 |doi=10.1371/journal.pone.0245897 |issn=1932-6203 |pmc=7842898 |pmid=33507987 |bibcode=2021PLoSO..1645897S |doi-access=free }}</ref><ref>{{Cite journal |last=Karapanagiotis |first=Ioannis |date=2019-01-29 |title=A Review on the Archaeological Chemistry of Shellfish Purple |journal=Sustainability |language=en |volume=11 |issue=13 |page=3595 |doi=10.3390/su11133595 |bibcode=2019Sust...11.3595K |issn=2071-1050 |doi-access=free }}</ref>

As early as the 15th century BC, the citizens of [[Place:Sidon|Sidon]] and [[Place:Tyre, Lebanon|Tyre]], two cities on the coast of Ancient [[History:Phoenicia|Phoenicia]] (present day Lebanon), were producing purple dye from a sea snail called the [[Biology:Bolinus brandaris|spiny dye-murex]].<ref name="Ball, Philip p. 290">Ball, Philip, ''Bright Earth; Art and the Invention of Colour''.  p. 290</ref> Clothing colored with the Tyrian dye was mentioned in both the ''[[Religion:Iliad|Iliad]]'' of [[Software:Homer|Homer]] and the ''Aeneid''  of Virgil.<ref name="Ball, Philip p. 290" /> The deep, rich purple dye made from this snail became known as Tyrian purple.<ref>Anne Varichon, ''Couleurs-pigments dans les mains des peuples'', p. 135–138</ref>

The process of making the dye was long, difficult and expensive. Thousands of the tiny snails had to be found, their shells cracked, the snail removed. Mountains of empty shells have been found at the ancient sites of Sidon and Tyre. The snails were left to soak, then a tiny gland was removed and the juice extracted and put in a basin, which was placed in the sunlight. There, a remarkable transformation took place. In the sunlight the juice turned white, then yellow-green, then green, then violet, then a red which turned darker and darker. The process had to be stopped at exactly the right time to obtain the desired color, which could range from a bright crimson to a dark purple, the color of dried blood. Then either wool, linen or silk would be dyed. The exact hue varied between crimson and violet, but it was always rich, bright and lasting.<ref>Anne Varichon, ''Couleurs-pigments dans les mains des peuples'', p. 135</ref>

Tyrian purple became the color of kings, nobles, priests and magistrates all around the Mediterranean. It was mentioned in the [[Religion:Hebrew Bible|Hebrew Bible]] ([[Religion:Old Testament|Old Testament]]); in the Book of Exodus, God instructs [[Biography:Moses|Moses]] to have the Israelites bring him an offering including cloth "of blue, and purple, and scarlet,"<ref>KJV Book of Exodus 25:4</ref> to be used in the curtains of the Tabernacle and the garments of priests. The term used for purple in the 4th-century [[Religion:Vulgate|Latin Vulgate]] version of the Bible passage is ''purpura'' or Tyrian purple.<ref name="Bible Gateway">{{cite web | title=Biblia Sacra Vulgata |website=Bible Gateway | url=https://www.biblegateway.com/passage/?search=Exodus+25&version=VULGATE | language=la | access-date=2020-05-19}}</ref> In the ''[[Religion:Iliad|Iliad]]'' of [[Software:Homer|Homer]], the belt of Ajax is purple, and the tails of the horses of Trojan warriors are dipped in purple. In the ''[[Religion:Odyssey|Odyssey]]'', the blankets on the wedding bed of Odysseus are purple. In the poems of [[Biology:Sappho|Sappho]] (6th century BC) she celebrates the skill of the dyers of the Greek kingdom of Lydia who made purple footwear, and in the play of [[Biography:Aeschylus|Aeschylus]] (525–456 BC), Queen Clytemnestra welcomes back her husband Agamemnon by decorating the palace with purple carpets. In 950 BC, King Solomon was reported to have brought artisans from Tyre to provide purple fabrics to decorate the Temple of Jerusalem.<ref>Anne Varichon (2000), ''Couleurs: pigments et teintures dans les mains des peuples'', p.&nbsp;136</ref>

Alexander the Great (when giving imperial audiences as the basileus of the Macedonian Empire), the basileus of the [[Place:Seleucid Empire|Seleucid Empire]], and the kings of Ptolemaic Egypt all wore Tyrian purple.

The Roman custom of wearing purple togas may have come from the Etruscans; an Etruscan tomb painting from the 4th century BC shows a nobleman wearing a deep purple and embroidered toga.

In Ancient Rome, the ''Toga praetexta'' was an ordinary white toga with a broad purple stripe on its border. It was worn by freeborn Roman boys who had not yet come of age,<ref>Liv. xxiv. 7, 2. As cited by ''The Dictionary of Greek and Roman Antiquities''.</ref> curule magistrates,<ref>cf. Cic. ''post red. in Sen.'' 5, 12. As cited by ''The Dictionary of Greek and Roman Antiquities''.</ref><ref>Zonar. vii. 19.  As cited by ''The Dictionary of Greek and Roman Antiquities''</ref> certain categories of priests,<ref>Liv. xxvii. 8, 8; xxxiii. 42. As cited by ''The Dictionary of Greek and Roman Antiquities''</ref> and a few other categories of citizens.

The ''Toga picta'' was solid purple, embroidered with gold. During the [[Place:Roman Republic|Roman Republic]], it was worn by generals in their triumphs, and by the Praetor Urbanus when he rode in the chariot of the gods into the circus at the Ludi Apollinares.<ref>cf. Liv. v. 41, 2. As cited by ''The Dictionary of Greek and Roman Antiquities''.</ref> During the Empire, the ''toga picta'' was worn by magistrates giving public gladiatorial games, and by the [[Software:Consul|consul]]s, as well as by the emperor on special occasions.

During the Roman Republic, when a triumph was held, the general being honored wore an entirely purple toga bordered in gold, and Roman Senators wore a toga with a purple stripe. However, during the [[Place:Roman Empire|Roman Empire]], purple was more and more associated exclusively with the emperors and their officers.<ref>{{cite web|url=http://www.mmdtkw.org/VPurple.html |title=Tyrian Purple in Ancient Rome |publisher=Mmdtkw.org |access-date=2012-12-29}}</ref> Suetonius claims that the early emperor [[Biography:Caligula|Caligula]] had the King of Mauretania murdered for the splendor of his purple cloak, and that [[Biography:Nero|Nero]] forbade the use of certain purple dyes.<ref>{{cite book|url=https://penelope.uchicago.edu/Thayer/e/roman/texts/suetonius/12caesars/home.html|title=The Lives of the Twelve Caesars|last=Suetonius|series=Loeb Classical Library|publisher=Heinemann|publication-date=1914|year=121|translator-last=Rolfe|translator-first=John Carew|translator-link=John Carew Rolfe|language=la, en|access-date=2017-03-28}}</ref> In the late empire the sale of purple cloth became a state monopoly protected by the death penalty.<ref name="Marzano2013">{{cite book|author=Annalisa Marzano|title=Harvesting the Sea: The Exploitation of Marine Resources in the Roman Mediterranean|url=https://books.google.com/books?id=hQ0oAAAAQBAJ|date=1 August 2013|publisher=OUP Oxford|isbn=978-0-19-967562-3|page=150}}</ref>

According to the [[Religion:New Testament|New Testament]], Jesus Christ, in the hours leading up to [[Religion:Crucifixion of Jesus|his crucifixion]], was dressed in purple (πορφύρα: ''porphura'') by the Roman garrison to mock his claim to be '[[Religion:Jesus, King of the Jews|King of the Jews]]'.<ref>Mark 15:17 and 20</ref>

The actual color of Tyrian purple seems to have varied from a reddish to a bluish purple. According to the Roman writer Vitruvius, (1st century BC), the [[Biology:Murex|murex]] shells coming from northern waters, probably ''[[Biology:Bolinus brandaris|Bolinus brandaris]]'', produced a more bluish color than those of the south, probably ''[[Biology:Hexaplex trunculus|Hexaplex trunculus]]''. The most valued shades were said to be those closer to the color of dried blood, as seen in the mosaics of the robes of the Emperor Justinian in Ravenna. The chemical composition of the dye from the murex is close to that of the dye from [[Indigo|indigo]], and indigo was sometimes used to make a counterfeit Tyrian purple, a crime which was severely punished. What seems to have mattered about Tyrian purple was not its color, but its luster, richness, its resistance to weather and light, and its high price.<ref>John Gage (2009), ''La Couleur dans l'art'', p.&nbsp;148–150.</ref>

In modern times, Tyrian purple has been recreated, at great expense. When the German chemist Paul Friedander tried to recreate Tyrian purple in 2008, he needed twelve thousand mollusks to create 1.4 ounces of dye, enough to color a handkerchief. In the year 2000, a gram of Tyrian purple made from ten thousand mollusks according to the original formula cost two thousand euros.<ref>Eva Heller, ''Psychologie de la couleur: effets et symboliques'', p.&nbsp;163</ref><ref>Phillip Ball (2001), ''Bright Earth, Art, and the Invention of Colour'', p.&nbsp;291</ref>

==== China ====
{{main|Han purple and Han blue}}
In ancient China, purple was obtained not through the Mediterranean mollusk, but [[Biology:Lithospermum erythrorhizon|purple gromwell]]. The dye obtained did not easily adhere to fabrics, making purple fabrics expensive. Purple became a fashionable color in the state of Qi (齊, 1046 BC–221 BC) because its ruler, Duke Huan of Qi, developed a preference for it. As a result, the price of purple fabric was over five times that of plain fabric. His minister, [[Biography:Guan Zhong|Guan Zhong]] (管仲), eventually convinced him to relinquish this preference.

China was the first culture to develop a synthetic purple color.<ref name="Thieme">Thieme, C. 2001. (translated by M.

An old hypothesis suggested links between the Chinese purple and blue and [[Egyptian blue]], however, molecular structure analysis and evidence such as the absence of lead in Egyptian blue and the lack of examples of Egyptian blue in China, argued against the hypothesis.<ref name="Liu"/><ref>{{cite web|url= https://www-ssrl.slac.stanford.edu/content/science/highlight/2007-03-30/ancient-warriors-and-origin-chinese-purple |title= Ancient Warriors and the Origin of Chinese Purple |website=Stanford University |date= 30 March 2007 }}</ref> The use of quartz, barium, and lead components in [[Engineering:Ancient Chinese glass|ancient Chinese glass]] and Han purple and Han blue has been used to suggest a connection between glassmaking and the manufacture of pigments,<ref name="FitzHugh and Zycherman 1983">FitzHugh, E.

Purple was regarded as a secondary color in ancient China. In classical times, secondary colors were not as highly prized as the five primary colors of the Chinese spectrum, and purple was used to allude to impropriety, in contrast to crimson, which was deemed a primary color and symbolized legitimacy. Nevertheless, by the 6th century AD, purple was ranked above crimson. Several changes to the ranks of colors occurred after that time.

=== Purple in the Byzantine Empire and Carolingian Europe ===
Through the early Christian era, the rulers of the [[Place:Byzantine Empire|Byzantine Empire]] continued the use of purple as the imperial color, for diplomatic gifts, and even for imperial documents and the pages of the Bible. Gospel manuscripts were written in gold lettering on parchment that was colored Tyrian purple.<ref>Varichon, Anne ''Colors: What They Mean and How to Make Them'' New York:2006 Abrams Page 140 – This information is in the caption of a color illustration showing an 8th-century manuscript page of the Gospel of Luke written in gold on Tyrian purple parchment.</ref> Empresses gave birth in the Purple Chamber, and the emperors born there were known as "born to the purple," to separate them from emperors who won or seized the title through political intrigue or military force. Bishops of the Byzantine church wore white robes with stripes of purple, while government officials wore squares of purple fabric to show their rank.

In western Europe, the Emperor Charlemagne was crowned in 800 wearing a mantle of Tyrian purple, and was buried in 814 in a shroud of the same color, which still exists (see below). However, after the fall of Constantinople to the Ottoman Turks in 1453, the color lost its imperial status. The great dye works of Constantinople were destroyed, and gradually [[Scarlet (color)|scarlet]], made with dye from the [[Biology:Cochineal|cochineal]] insect, became the royal color in Europe.<ref>Anne Varichon (2000), ''Couleurs: pigments et teintures dans les mains des peuples'', p.&nbsp;137–38</ref>

=== The Middle Ages and Renaissance ===
In 1464, Pope Paul II decreed that cardinals should no longer wear Tyrian purple, and instead wear scarlet, from [[Biology:Kermes (dye)|kermes]] and alum,<ref>{{cite web|author=LaVerne M. Dutton|title= ''Cochineal: A Bright Red Animal Dye''|page=57|url=http://www.cochineal.info/pdf/Ch-5-History-Dyes-Dying-Industry-Old-World-Cochineal-Industry.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.cochineal.info/pdf/Ch-5-History-Dyes-Dying-Industry-Old-World-Cochineal-Industry.pdf |archive-date=2022-10-09 |url-status=live|website=Cochineal.info}}</ref> since the dye from Byzantium was no longer available. Bishops and archbishops, of a lower status than cardinals, were assigned the color purple, but not the rich Tyrian purple. They wore cloth dyed first with the less expensive [[Indigo|indigo]] blue, then overlaid with red made from [[Biology:Kermes (dye)|kermes]] dye.<ref>Eva Heller, ''Psychologie de la couleur: effets et symboliques'', p.&nbsp;165.</ref><ref>Elena Phipps, ''Cochineal red: The art history of a color'', p.&nbsp;26.</ref>

While purple was worn less frequently by medieval and [[Philosophy:Renaissance|Renaissance]] kings and princes, it was worn by the professors of many of Europe's new universities.  Their robes were modeled after those of the clergy, and they often wore square/violet or purple/violet caps and robes, or black robes with purple/violet trim. Purple/violet robes were particularly worn by students of divinity.

Purple and violet also played an important part in the religious paintings of the Renaissance. Angels and the Virgin Mary were often portrayed wearing purple or violet robes.

=== 18th and 19th centuries ===
In the 18th century, purple was still worn on occasion by Catherine the Great and other rulers, by bishops and, in lighter shades, by members of the aristocracy, but rarely by ordinary people, because of its high cost. But in the 19th century, that changed.

In 1856, an eighteen-year-old British chemistry student named William Henry Perkin was trying to make a synthetic [[Chemistry:Quinine|quinine]]. His experiments produced instead the first synthetic aniline dye, a purple shade called [[Chemistry:Mauveine|mauveine]], shortened simply to [[Mauve|mauve]]. It took its name from the mallow flower, which is the same color.<ref name="Grovier">{{Cite web|url=http://www.bbc.com/culture/story/20180801-tyrian-purple-the-regal-colour-taken-from-mollusc-mucus|title=Tyrian Purple: The disgusting origins of the colour purple|last=Grovier|first=Kelly|date=August 2018 |language=en|access-date=2018-08-14}}</ref> The new color quickly became fashionable, particularly after Queen Victoria wore a silk gown dyed with mauveine to the Royal Exhibition of 1862. Prior to Perkin's discovery, mauve was a color which only the aristocracy and rich could afford to wear. Perkin developed an industrial process, built a factory, and produced the dye by the ton, so almost anyone could wear mauve. It was the first of a series of modern industrial dyes which completely transformed both the chemical industry and fashion.<ref>{{cite book|author=Garfield, S.|year=2000|title=Mauve: How One Man Invented a Colour That Changed the World |publisher=Faber and Faber, London, UK|isbn=978-0-571-20197-6}}</ref>

Purple was popular with the pre-Raphaelite painters in Britain, including Arthur Hughes, who loved bright colors and romantic scenes.

=== 20th and 21st centuries ===
At the turn of the century, purple was a favorite color of the Austrian painter Gustav Klimt, who flooded his pictures with sensual purples and violets.

In the 20th century, purple retained its historic connection with royalty; George VI (1896–1952), wore purple in his official portrait, and it was prominent in every feature of the coronation of Elizabeth II in 1953, from the invitations to the stage design inside Westminster Abbey. But at the same time, it was becoming associated with social change; with the Women's Suffrage movement for the right to vote for women in the early decades of the century, with [[Social:Feminism|Feminism]] in the 1970s, and with the psychedelic drug culture of the 1960s.

In the early 20th century, purple, green, and white were the colors of the Women's Suffrage movement, which fought to win the right to vote for women, finally succeeding with the 19th Amendment to the U.S. Constitution in 1920. Later, in the 1970s, in a tribute to the Suffragettes, it became the color of the women's liberation movement.<ref>Eva Heller, ''Psychologie de la couleur: effets et symboliques'', image 75–76.</ref>

In the concentration camps of [[Place:Nazi Germany|Nazi Germany]], prisoners who were members of non-conformist religious groups, such as the Jehovah's Witnesses, were required to wear a [[Purple triangle|purple triangle]].<ref>{{Cite web |url=https://www.pbs.org/independentlens/knocking/holocaust.html |title=Independent Lens .

During the 1960s and early 1970s, it was also associated with counterculture, psychedelics, and musicians like Jimi Hendrix with his 1967 song "Purple Haze", or the English rock band of Deep Purple which formed in 1968. Later, in the 1980s, it was featured in the song and album ''Purple Rain'' (1984) by the American musician Prince.

The Purple Rain Protest was a protest against apartheid that took place in [[Place:Cape Town|Cape Town]], South Africa on 2 September 1989, in which a police [[Chemistry:Water cannon|water cannon]] with purple dye sprayed thousands of demonstrators. This led to the slogan ''The Purple Shall Govern''.

The violet or purple necktie became very popular at the end of the first decade of the 21st century, particularly among political and business leaders. It combined the assertiveness and confidence of a red necktie with the sense of peace and cooperation of a blue necktie, and it went well with the blue business suit worn by most national and corporate leaders.<ref name="ReferenceA">Eva Heller, Psychologie de la couleur: effets et symboliques.</ref>

The meanings of the color terms violet and purple varies even among native speakers of English, for example between United Kingdom and United States.<ref name="Computational evidence of first ext">{{cite journal |last1=Tager |first1=A. |last2=Kirchner |first2=E. |last3=Fedorovskaya |first3=E. |title=Computational evidence of first extensive usage of violet in the 1860s |journal=Color Research & Application |date=2021 |volume=46 |issue=5 |pages=961–977 |doi=10.1002/col.22638|s2cid=233671776 }}</ref> Optics research on purple and violet contains contributions of authors from different countries and different native languages, it is likely to be inconsistent in the use and meaning of the two colors.

According to some speakers/authors of English, purple, unlike violet, is not one of the colors of the [[Physics:Visible spectrum|visible spectrum]].<ref name="StClair">{{Cite book|title=The Secret Lives of Colour|last=St. Clair|first=Kassia|publisher=John Murray|year=2016|isbn=978-1-4736-3081-9|location=London|page=159|oclc=936144129}}</ref> It was not one of the colors of the rainbow identified by [[Biography:Isaac Newton|Isaac Newton]]. According to some authors, purple does not have its own [[Wavelength|wavelength]] of light. For this reason, it is sometimes called a ''non-spectral color''. According to some speakers of English, purple is simply a combination, in various proportions, of two primary colors, red and blue.<ref>{{cite journal |last1=Matschi |first1=M. |title=Color terms in English: Onomasiological and Semasiological aspects |journal=Onomasiology Online |date=2005 |volume=5 |pages=56–139 }}</ref> According to other speakers of English, the same range of colors is called violet.<ref name="The ANLAB colour system and the dye">{{cite journal|last1=Cooper|first1=A.C.|last2=McLaren|first2=K.|date=1973|title=The ANLAB colour system and the dyer's variables of "shade" and strength|journal=Journal of the Society of Dyers and Colourists|volume=89|issue=2|pages=41–45|doi=10.1111/j.1478-4408.1973.tb03128.x}}</ref>

In some textbooks of [[Color theory|color theory]], and depending on the geographical-cultural origin of the author, a "purple" is defined as any non-spectral color between [[Violet (color)|violet]] and red (excluding violet and red themselves).<ref name="gilbert222" /> In that case, the spectral color violet would not be shades of purple. For other speakers of English, these colors are shades of purple.

In the traditional color wheel long used by painters, purple is placed between crimson and violet.<ref>See ''Oxford English Dictionary'' definition</ref> However, also here there is much variation in color terminology depending on cultural background of the painters and authors, and sometimes the term violet is used and placed in between red and blue on the traditional color wheel. In a slightly different variation, on the [[HSV color space|color wheel]], purple is placed between magenta and violet. This shade is sometimes called electric purple (see [[Shades of purple|shades of purple]]).<ref>Lanier F. (editor) ''The Rainbow Book'' Berkeley, California: Shambhala Publications and The Fine Arts Museums of San Francisco (1976) (Handbook for the Summer 1976 exhibition ''The Rainbow Art Show'' which took place primarily at the De Young Museum but also at other museums) Portfolio of color wheels by famous theoreticians—see Rood color wheel (1879) p. 93</ref>

In the [[RGB color model]], named for the colors red, green, and blue, used to create all the colors on a computer screen or television, the range of purples is created by mixing red and blue light of different intensities on a black screen. The standard [[HTML]] color purple is created by red and blue light of equal intensity, at a brightness that is between full power and darkness.

In color printing, purple is sometimes represented by the color [[Magenta|magenta]] mixed with cyan or black or sometimes by mixing magenta with red or blue. It can also be created by mixing just red and blue alone, but in that case the purple is less bright, with lower
saturation or intensity.  A less bright purple can also be created with light or paint by adding a certain quantity of the third primary color (green for light or yellow for pigment).

=== Pigments ===
*[[Chemistry:Hematite|Hematite]] and [[Chemistry:Manganese|manganese]] are the oldest pigments used for the color purple. They were used by [[History:Neolithic|Neolithic]] artists in the form of sticks, like charcoal, or ground and powdered and mixed with fat, and used as a paint. Hematite is a reddish [[Chemistry:Iron oxide|iron oxide]] which, when ground coarsely, makes a purple pigment. One such pigment is caput mortuum, whose name is also used in reference to [[Mummy brown|mummy brown]]. The latter is another pigment containing hematite and historically produced with the use of mummified corpses.<ref>{{cite web|url=https://www.youtube.com/watch?v=rApTzWboLrA |archive-url=https://ghostarchive.org/varchive/youtube/20211211/rApTzWboLrA| archive-date=2021-12-11 |url-status=live|title=The Library of Rare Colors|last=Tom|first=Scott|date=18 March 2019|access-date=8 May 2019|via=YouTube}} </ref> Some of its compositions produce a purple color and may be called "mummy violet".<ref>{{cite web| title =Mummy Brown| publisher =naturalpigments.com| url =http://www.naturalpigments.com/detail.asp?PRODUCT_ID=460-22S| access-date =2008-02-08| archive-url =https://web.archive.org/web/20040816025813/http://www.naturalpigments.com/detail.asp?PRODUCT_ID=460-22S| archive-date =2004-08-16}}</ref> Manganese was also used in Roman times to color glass purple.<ref>Anne Varichon, ''Couleurs-pigments et teintures dans les mains des peuples'', p. 146</ref>
*Han purple was the first synthetic purple pigment, invented in China in about 700 BC. It was used in wall paintings and pottery and other applications.  In color, it was very close to [[Indigo|indigo]], which had a similar chemical structure.  Han purple was very unstable, and sometimes was the result of the chemical breakdown of Han blue.

During the Middle Ages, artists usually made purple by combining red and blue pigments; most often blue azurite or lapis-lazuli with red ochre, [[Chemistry:Cinnabar|cinnabar]], or [[Minium (pigment)|minium]]. They also combined lake colors made by mixing dye with powder; using woad or indigo dye for the blue, and dye made from [[Biology:Cochineal|cochineal]] for the red.<ref name="Anne Carichon 2000 p.&nbsp;133" />

*Cobalt violet was the first modern synthetic color in the purple family, manufactured in 1859. It was found, along with [[Chemistry:Cobalt blue|cobalt blue]], in the palette of Claude Monet, Paul Signac, and Georges Seurat. It was stable, but had low tinting power and was expensive, so quickly went out of use.<ref>Isabelle Roelofs, ''La Couleur Expliquée aux artistes, 52–53.''</ref>
*[[Chemistry:Manganese violet|Manganese violet]] was a stronger color than cobalt violet, and replaced it on the market.
*[[Chemistry:Quinacridone|Quinacridone]] violet, one of a modern synthetic organic family of colors, was discovered in 1896 but not marketed until 1955.  It is sold today under a number of brand names.

=== Dyes ===
The most famous purple dye in the ancient world was [[Tyrian purple]], made from a type of sea snail called the [[Biology:Murex|murex]], found around the Mediterranean. (See history section above).<ref name="StClair" />

In western [[Place:Polynesia|Polynesia]], residents of the islands made a purple dye similar to Tyrian purple from the [[Biology:Sea urchin|sea urchin]]. In Central America, the inhabitants made a dye from a different sea snail, the [[Biology:Purpura (gastropod)|purpura]], found on the coasts of Costa Rica and Nicaragua. The Mayans used this color to dye fabric for religious ceremonies, while the Aztecs used it for paintings of ideograms, where it symbolized royalty.<ref name="Anne Carichon 2000 p.&nbsp;133">Anne Carichon (2000), ''Couleurs: pigments et teintures dans les mains des peuples''. p.&nbsp;133.</ref>

In the Middle Ages, those who worked with blue and black dyes belonged to separate guilds from those who worked with red and yellow dyes, and were often forbidden to dye any other colors than those of their own guild.<ref name="StClair2">{{Cite book|title=The Secret Lives of Colour|last=St. Clair|first=Kassia|publisher=John Murray|year=2016|isbn=978-1-4736-3081-9|location=London|page=211|oclc=936144129}}</ref> Most purple fabric was made by the dyers who worked with red, and who used dye from [[Biology:Rubia|madder]] or [[Biology:Cochineal|cochineal]], so medieval violet colors were inclined toward red.<ref>{{Cite web |last=Clayton |first=Graham |date=2016-03-23 |title=What colour are you?

[[Biology:Orcein|Orcein]], or ''purple moss'', was another common purple dye. It was known to the ancient Greeks and Hebrews, and was made from a Mediterranean [[Biology:Lichen|lichen]] called archil or dyer's moss ([[Biology:Roccella tinctoria|Roccella tinctoria]]), combined with an ammoniac, usually urine. Orcein began to achieve popularity again in the 19th century, when violet and purple became the color of demi-mourning, worn after a widow or widower had worn black for a certain time, before he or she returned to wearing ordinary colors.<ref>Anne Carichon (2000), ''Couleurs: pigments et teintures dans les mains des peuples''. p.&nbsp;144.</ref>

From the Middle Ages onward, purple dyes for the clothing of common people were often made from the [[Biology:Blackberry|blackberry]] or other red fruit of the genus [[Biology:Rubus|rubus]], or from the mulberry. All of these dyes were more reddish than bluish, and faded easily with washing and exposure to sunlight.

A popular new dye which arrived in Europe from the New World during the Renaissance was made from the wood of the logwood tree (H''aematoxylum campechianum''), which grew in Spanish Mexico. Depending on the different minerals added to the dye, it produced a blue, red, black or, with the addition of [[Chemistry:Alum|alum]], a purple color, it made a good color, but, like earlier dyes, it did not resist sunlight or washing.

In the 18th century, chemists in England, France and Germany began to create the first synthetic dyes. Two synthetic purple dyes were invented at about the same time. '''Cudbear''' is a dye extracted from orchil [[Biology:Lichen|lichen]]s that can be used to dye wool and [[Chemistry:Silk|silk]], without the use of [[Engineering:Mordant|mordant]]. Cudbear was developed by Dr Cuthbert Gordon of Scotland: production began in 1758, The lichen is first boiled in a solution of [[Chemistry:Ammonium carbonate|ammonium carbonate]]. The mixture is then cooled and [[Chemistry:Ammonia|ammonia]] is added and the mixture is kept damp for 3–4 weeks. Then the lichen is dried and ground to powder. The manufacture details were carefully protected, with a ten-feet high wall being built around the manufacturing facility, and staff consisting of Highlanders sworn to secrecy.

'''French purple''' was developed in France at about the same time. The lichen is extracted by urine or ammonia. Then the extract is acidified, the dissolved dye precipitates and is washed. Then it is dissolved in ammonia again, the solution is heated in air until it becomes purple, then it is precipitated with [[Chemistry:Calcium chloride|calcium chloride]]; the resulting dye was more solid and stable than other purples.

'''Cobalt violet''' is a synthetic pigment that was invented in the second half of the 19th century, and is made by a similar process as [[Chemistry:Cobalt blue|cobalt blue]], cerulean blue  and [[Chemistry:Cobalt green|cobalt green]]. It is the violet pigment most commonly used today by artists. In spite of its name, this pigment produces a purple rather than violet color.<ref name="Computational evidence of first ext"/>

In the 1950s, a new family of purple and violet synthetic organic pigments called [[Chemistry:Quinacridone|quinacridone]] came onto the market. It had originally been discovered in 1896, but were not synthesized until 1936, and not manufactured until the 1950s.

=== Anthocyanins ===
Certain grapes, eggplants, pansies and other fruits, vegetables and flowers may appear purple due to the presence of natural pigments called anthocyanins. These pigments are found in the leaves, roots, stems, vegetables, fruits and flowers of all plants. They aid [[Earth:Photosynthesis|photosynthesis]] by blocking harmful wavelengths of light that would damage the leaves. In flowers, the purple anthocyanins help attract insects who pollinate the flowers. Not all anthocyanins are purple; they vary in color from red to purple to blue, green, or yellow, depending upon the level of their [[Chemistry:PH|pH]].

=== Purple mountains phenomenon ===

It has been observed that the greater the distance between a viewers eyes and mountains, the lighter and more blue or purple they will appear. This phenomenon, long recognized by [[Biography:Leonardo da Vinci|Leonardo da Vinci]] and other painters, is called [[Aerial perspective|aerial perspective]] or atmospheric perspective. The more distant the mountains are, the less contrast the eye sees between the mountains and the sky.

The bluish color is caused by an optical effect called [[Physics:Rayleigh scattering|Rayleigh scattering]]. The sunlit sky is blue because air scatters short-[[Wavelength|wavelength]] light more than longer wavelengths. Since blue light is at the short wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than long wavelength red light. The result is that the human eye perceives blue when looking toward parts of the sky other than the sun.<ref>"[http://search.eb.com/eb/article-9062822 Rayleigh scattering] {{Webarchive|url=https://web.archive.org/web/20221031205802/https://academic.eb.com/ |date=2022-10-31 }}." ''Encyclopædia Britannica''. 2007. Encyclopædia Britannica Online. 16 Nov. 2007.</ref>

At sunrise and sunset, the light is passing through the atmosphere at a lower angle, and traveling a greater distance through a larger volume of air. Much of the green and blue is scattered away, and more red light comes to the eye, creating the colors of the sunrise and sunset and making the mountains look purple.

The phenomenon is referenced in the song "America the Beautiful", where the lyrics refer to "purple mountains' majesty" among other features of the United States landscape. A [[List of Crayola crayon colors|Crayola]] crayon called Purple Mountain Majesty in reference to the lyric was first formulated in 1993.
