Query: Worth every penny

Anyone serious about improving the color in their paintings should own this book. The reproductions are clear and lucious. The work is done in palette knife so the color notes are clean. It takes you step by step through several still life settings and excercises and shows how the objects were first divided into shadow and light patterns and then breaks down to the finer nuances of color. It teaches the student how to look closer and see the subtle temperature shifts of color. There are also several reproductions of completed paintings in the back that utilize the approach. Fortunately I bought it while it was still in print and cheap, but, I'd pay $60 for it if I didn't own it already.
