Color Interaction
Simultaneous Contrast. No eye is so astute that it cannot be tricked by color, however much we tend to think of sight as the most trustworthy of all our senses. Nor do we realize how much sight is influenced by habit and cultural persuasions. Most of the ambiguities of color may be related to the phenomenon known as simultaneous contrast, the way colors affect one another mutually by seeming to alter one another in both hue and value. This, in turn, is related to the negative afterimage. Only in the case of true complementaries do two juxtaposed colors appear not to influence each other, except to make each other seem more brilliant. Yet, even in these instances, there may be discrepancies. One important law of contrast states that great extremes of value inhibit color intensity. If the Impressionists understood anything well, they understood this. [p. 101]
