Question

Quizplus · Accepted Answer

The trichromatic theory, which posits that the human eye has three types of receptors sensitive to red, green, and blue light, has difficulty explaining negative afterimages. This phenomenon is better accounted for by the opponent-process theory, which suggests that color perception is controlled by the activity of two opponent systems: a blue-yellow mechanism and a red-green mechanism. Negative afterimages occur because the activation of one color in a pair inhibits the activation of the other color, leading to the perception of the opposite color after the original stimulus is removed.
