Color & Vision

Parts of the Eye

Cone Response 3 types of cones in retina Each responds more strongly to wavelength for which it is named As the cones are stimulated in different proportions, our visual system constructs the colors we see.

Primary Colors Red Blue Green

Complementary Colors When two of the three additive primary colors are combined: Red + Blue = Magenta Red + Green = Yellow Blue + Green = Cyan Two colors that combine to produce white are called complementary Magenta + ? = White Yellow + ? = White Cyan + ? = White
