Afterimages are a phenomenon where staring at a color for an extended period results in a temporary afterimage of the complementary color. This can be explained by the opponent-process theory, which proposes that each of the three cone types in the eye are paired with an opponent color (red/green, blue/yellow, black/white) and reacting to one color in the pair inhibits the response to the other. Staring at a color for a long time fatigues the cones responding to that color, causing the opponent cones to respond more strongly, leading to an afterimage of the opponent color.
