In-Depth Information
On a white background, primary yellow will appear somewhat less intense—white is the ultimate
in saturation—but on a black background, the same yellow will become extremely intense. Against
a middle value of gray, the yellow decreases in saturation unless the surrounding value (darkness
or lightness) is similar.
The same violet is presented against three fields of varied intensity. Against a similarly intense vi-
olet of slightly different hue, the base color appears desaturated. Against a neutral gray, the base
violet appears moderately intense. Juxtaposing the base violet with a field of a very different hue,
but one that is of similar value, again increases the base violet's apparent saturation.
