I've been learning so much from this book since I bought it 2 months ago. 'Color and Light: A Guide for the Realist Painter' by James Gurney. Excellent comprehensive resource for any painter (regardless of medium) wanting to understand and incorporate more of those two devices into their work.
(Available online and in most
book stores. If you buy it directly from James Gurney, he'll even sign
it for you: http://jamesgurney.com/site/213/color-and-light-a-guide-for-the-realist-painter )
