'In visual perception a color is almost never seen as it really is - as it physically is. This first makes color the most relative medium in art. In order to use color effectively it is necessary to recognize that color deceives continually. To this end, the beginning is not a study of color systems.'
(Josef Albers, Interaction of Color, New Haven 1963, p. 1.)
