The opponent process theory proposes that we have color receptors in our eyes that are divided into three pairs of opposing colors: blue-yellow, red-green, and black-white. When one color is stimulated, its opponent color is inhibited, resulting in an afterimage of the opposite color. Therefore, the antagonistic color of a pair will overcompensate following release from inhibition, leading to an afterimage of the opposite color.
