Color, any attempt to apply the scientific principles of color vision in the making of a picture must surely fail if it be not granted at the out set that it is only to a limited degree that those principles can apply. Color appreciation is as much a psychical as a physiological, and indeed, it is psychical not only with regard to the objective impression itself, but also with regard to the subjective, the associational mental process. Previous knowledge and training, experience traditions, the association of color impressions with impressions previously received through other senses and stored away as memories, all play a part in determining the effect which a color or a pattern of opposed colors has upon us. But even granting all this, there are many of the physical and physiological laws of color vision which must be adhered to before we can expect to produce these effects.
