This property of human vision, called trichromacy, arises because the retina the layer of nerve cells in the eye that captures light and transmits visual information to the brain uses only three types of light-absorbing pigments for color vision.

The result casts some typical ideas of his time, notably the emphasis on trichromacy and the description of vision, into a new vocabulary without accompanying conceptual changes.
