Bezold Effect
The Bezold Effect, also referred to as the "assimilation effect", is an optical illusion where a color's hue or value is affected by the color or colors surrounding it.
Discovery
The Bezold effect was first discovered by 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.
Description
When looking at a specific hue, it can appear to change in appearance depending on what colors surround it. A yellow box surrounded by blue will look darker than a yellow box surrounded by red. Often, the surrounded color seems to take on a tint of the color that surrounds it; red boxes surrounded by blue will appear more bluish than those surrounded by white.
Explanation
The reasons behind the Bezold effect remain a neurological puzzle.[1]
Applications
Knowledge of the Bezold effect is useful in fields such as graphic design, where artists can use combinations of adjacent colors to create the effect they desire.
