The Opponent Process Theory of Color Vision You do not see greenish-red because the opponent cells can only detect one of these colors at a time. How the Opponent Process Theory Differs From Trichromatic Theory. While the trichromatic theory makes clear some of the processes involved in how we see color, it does not explain all aspects of color vision.
