A)  trichromatic theory 
B)  dichromatic theory 
C)  opponent process theory 
D)  complementary colour theory

Opponent Process Theory

A theory that suggests emotional experiences are processed by opposing systems, one which is activated by the experience and another that produces the opposite effect to maintain emotional equilibrium.

Trichromatic Theory

A theory explaining how the human eye perceives color through the response of three types of cones sensitive to red, green, and blue light.
