Color Theory - Chicago Library
The ancient theory of color was that all colors were mixtures of darkness and light - black and white. Aristotle, for instance, held that dark crimson comes from the mixture of black with sunlight or firelight. It was Isaac Newton who first fully developed a theory of color based on a color wheel. Newton split white light into a spectrum by means of a prism and then wrapped the resulting spectrum around on itself to create the color wheel.
