Question

Afterimages are an important aspect of the opponent-process theory of color vision. According to this theory, color perception is based on the activity of three pairs of opponent cells. Each pair responds to opposite ends of the color spectrum (e.g. red-green, blue-yellow, black-white) and when one color is stimulated, the opposing color is inhibited. Afterimages occur when the cells that respond to a particular color become fatigued, and the opposite cells continue to fire, creating a sensation of the opposite color. This sensation remains even after the original stimulus is removed, which is why it is called an afterimage.
