Short description: Optical mixing of colors
Demonstration of the Bezold effect. The red seems lighter combined with the white, and darker combined with the black.

The Bezold effect is an optical illusion, named after a German professor of meteorology Wilhelm von Bezold (1837–1907), who discovered that a color may appear different depending on its relation to adjacent colors.

It happens when small areas of color are interspersed. An assimilation effect called the von Bezold spreading effect, similar to spatial color mixing, is achieved.

The opposite effect is observed when large areas of color are placed adjacent to each other, resulting in color contrast.
