Cyan, also called aqua, is the blue-green color that is between blue and green on a modern RGB color wheel.

The modern RGB color wheel replaced the traditional old-fashioned RYB color wheel because it is possible to display much brighter and more saturated colors using the primary and secondary colors of the RGB color wheel. In the terminology of color theory, RGB color space has a much larger color gamut than RYB color space.

The first recorded use of cyan as a color name in English was in 1879.[1]

Cerulean (/səˈrliən/), also spelled caerulean, is a shade of blue ranging between azure and a darker sky blue.

The first recorded use of cerulean as a colour name in English was in 1590.[3] The word is derived from the Latin word caeruleus, "dark blue, blue, or blue-green", which in turn probably derives from caerulum, diminutive of caelum, "heaven, sky".[4]

"Cerulean blue" is the name of a pigment. The pigment was discovered in the late eighteenth century and designated as cerulean blue in the nineteenth century.

alt=American teal duck (male)|thumb|Green-winged teal (male) Teal is a light greenish blue color. Its name comes from that of a bird — the Eurasian teal (Anas crecca) — which presents a similarly colored stripe on its head. The word is often used colloquially to refer to shades of cyan in general.

It can be created by mixing cyan into a green base, or deepened as needed with black or gray.[5] The complementary color of teal is pink. It is also one of the first group of 16 HTML/CSS web colors formulated in 1987. In the RGB model used to create colors on computer screens and televisions, teal is created by reducing the brightness of cyan to about one half.

Teal was a fad color during the 1990s, with, among others, many sports teams adopting the color for their uniforms.[6][7]
