Quizplus · Accepted Answer

The opponent-process theory, proposed by Ewald Hering, explains afterimages by suggesting that colors are perceived in terms of opposing pairs: red-green, blue-yellow, and black-white. This theory complements the trichromatic theory by explaining phenomena the latter cannot, such as afterimages and the fact that certain color combinations (like reddish-green) are never seen.
