colour mixing

"Also, mix warm with warm colors only, and cool with cool. That is to say, a warm yellow with a warm red or a warm blue. What are the warm blue? Cobalt blue is warm, Prussian Blue is warm. Ultramarine is cool, Cerulean is cool. Alizarin is cool on the red side, Cadmium Red is warm. Lemon yellow is cool, Cadmium Yellow warm. If you keep them in their own family of warm and cool, the colors will be cleaner, not muddy, and they will look beautiful in counterposition to one another."
