Quizplus · Accepted Answer

Ewald Hering first proposed the opponent-process theory of color vision in 1872, stating that our perception of color is determined by the activity of three opposing systems: black versus white, blue versus yellow, and red versus green. This theory has since been supported by research in neurophysiology.
