A new book on color by Al Gury was just published by Watson-Guptill this last year. Al was one of my most influential teachers when I was studying back in Philadephia; he is currently the chair of the painting department at the Pennsylvania Academy of Fine Arts there. Titled "Color for Painters: A Guide to Traditions and Practice," this is a very thorough book that should prove helpful for students and those artists just beginning their voyage into color exploration as well as interesting and thought-provoking for many who have been painting for years. (Here is another book that Al wrote a few years ago, this one on alla prima painting.)
This book covers a great range of topics including the history of color usage in art, how artists organize and conceptualize their color, and a whole lot more. I wouldn't be surprised at all is this became a staple in art classrooms.
