According to the opponent-process theory, cells in the visual system respond to complementary pairs of colors (e.g., red-green, blue-yellow). When one member of a pair is stimulated for a prolonged period of time, the cells become fatigued and the opposing member of the pair is perceived as an afterimage. For example, when you stare at a red object for a long time, the cells that process red become tired and when you look away, you briefly see a green afterimage.
