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
