Question

Quizplus · Accepted Answer

The opponent-process theory of color vision proposes that there are three types of opponent color channels: red-green, blue-yellow, and black-white. When one color in a pair is perceived, the other is inhibited. This theory can explain negative afterimages, where staring at a color produces an afterimage in the opposite color (e.g. staring at green produces a reddish afterimage).
