No study of color effect is complete unless it deals with at least three aspects: physics, physiology and psychology. This article covers only a phase of the author's 40-year study of color effect, but it goes into a problem not covered in the Universal Book of Color Science. The highlights of this article are:
1) The author has devised a formula for producing multiple colors out of two with a special instrument called Muto Chrome.
2) He has been able to establish physiologically that a colorless state looks colored.
3) He has completed a quantative analysis of a complementary after-image.
4) He has devised a method of more exact and more rapid color-matching.
