The retinex theory of color vision explains both color and brightness constancy. It posits that the visual system compares the light received by each area of an object to the light received by surrounding areas (context) to determine the color and brightness of the object. This helps us perceive colors and brightness consistently, even when lighting conditions change. The trichromatic theory explains how we perceive color (based on the activation of three types of cones in the retina), while the opponent-process theory explains the afterimage effect and how we perceive color in pairs of opponent colors (such as red-green or blue-yellow).
