If you know this title, you already know it's the Digital Lighter's Bible. Every page is wonderfully informative, and sports spectacularly full-color image examples to accomany the concepts (a big help when discussing color!!).
Some people are put off by it's lack of platform-specific information, but he's really illustrating concepts, not executions. I think this books gives you enough of a starting point that you can easily (or with a few Google searches) find your own methods.
If you're thinking of becoming a CG Lighter or Shader Writer - BUY THIS BOOK. Or better yet, buy the second edition!
