Complementary colors are in the greatest
possible contrast to one another.
When a color is looked at, the corresponding
nerves are excited, and if the gaze iscontinued for a considerable time, the
nerves become fatigued, while the other
nerves are resting. When the eye is
transferred to another surface the restednerves produce sympathetically an after-
image which is complementary in color to
the first color
