Trichromacy of Color Vision
Recall: Rods are sensitive to low lightlevels; cones are sensitive to colors
There are three types of cones, each oneof which is most responsive to a certain range of wavelengths
Trichromacy of Color Vision
Your brain is aware only of the response of the photoreceptor; since there is only one type of rod, there can be no color sensitivity

Trichromacy of Color Vision
What causes color blindness?
One or two types of cones are missing from the retina
Spectral Complementaries
Colors which when added togetherproduce white light.
This white light appears no differentlyto us than the white light made up ofthe entire spectrum.

Psychological Primary Colors
Why do Lego blocks have the colors they do?
