This is more readable, information rich, and practical than Tim Grey's well-written "Color Confidence" which had set a high standard.
Like most books on the subject, it starts with a color theory chapter. Besides being a pleasure to read, it is almost certain to teach something you didn't already know. Even a science whiz will be impressed at how gently, thoroughly, and coherently the topics are brought together.
Most of the remaining chapters can be read in isolation. Many will immediately focus on a chapter relating to their specific software and then proceed to the all important workflow chapter.
For those buying tools, the book offers excellent coverage of the major products including hardware (densiometers, colorimeters, spectrophotometers, targets, monitors, printers, and inks), profiling packages (Gretag-Macbeth, Monaco, etc), and ICC visualization/editing tools (ColorThink and such).
The book empowers you to make thoughtful choices on every Photoshop setting (black-points, colorspaces, rendering intents, etc). Also, the section on evaluating profiles is excellent. This topic is usually omitted from other books on the subject.
All in all, I give this one an A+.
