Quizplus · Accepted Answer

The trichromatic theory explains the first stage of visual processing, where three types of cones in the retina are responsible for detecting red, green, and blue light. The opponent process theory explains the processing that occurs in the visual pathway after information leaves the retina. It explains how cells in the visual system respond to color in an antagonistic manner, such as red vs. green and yellow vs. blue. These theories complement each other and explain different stages of visual processing.
