It's a great book for engineers working with color, as its principles are explained through color theory and the mathematical relationships between colors.
Most photoshop 'experts' are people who have dicked around with it forever and just haphazardly learned the tools, Margulis comes from a much more empirical place and shows how to manipulate color in ways that are more natural and less damaging to images by using as few tools as possible.
Additionally, you'll learn a ton about color theory, which is worthwhile by itself.
