Art: Yesterday, Today, and Tomorrow throws its light upon the color; the light of the color responds to that light. And the third light is the light of the eyes which see; therefore any given color is not the same to everybody, not only because the degree of light of every person is different, or the light which falls on the subject is different, or the degree of the color is different, but also because the element which that particular color represents produces a certain degree of response in an individual.
