The opponent process theory states that our perception of color is based on three types of opposing pairs of colors - red/green, blue/yellow, and black/white. This theory posits that when we see a color, it is signaled by neurons firing at different rates, with one set of neurons firing more quickly to one color and another set firing more quickly to its opposite color in the pair (i.e., red vs. green, blue vs. yellow, or black vs. white). This theory helps to explain some of the ways in which we perceive colors and the afterimages we see when looking at a bright color and then shifting our gaze to a neutral surface.
