Opponent Theory

A colour vision theory that states that the human eyes’ ability to perceive colour is controlled by three receptor complexes that act in an opposing way. It also says that the human eye needs four unique colours; yellow, red, green, and blue, for colour perception and that the rod and cone cells can only detect one colour at a time.
