I thought the book was a little whacked until I realized my monitor was out of calibration. I used the Eye-One Display 2 Monitor Calibrator to calibrate my monitor and now I am getting colors that are VERY close to the book.
There isn't much to say about it except that is it very easy to use, very intuitive, and will have you making better color choices without having to learn one single thing about color theory. You can be completely color-theory illiterate and still make great choices using this book.
In fact, you could be writing hex code for html on a monochrome monitor, while using this book, and still get it right!
The book is split up into sections based on color. "Combination of blue hues" is the first section cluster. Within that section is "Blues + neighboring hues", "Blues + opposing hues", "Blues + neutral hues", and "Blues + black and tints of black." These section clusters continue for Reds, Violets, Orange, Yellow, and Greens. At the end you will find "Mixed combinations of Saturated Hues", "Mixed Combinations of Semi-muted Hues", "Mixed Combination of Neutrals and Muted Hues", Mixed Combination of Neutrals and Saturated Hues."
I highly recommend this book, just be sure that your monitor is calibrated before you start complaining about the book's color numbers being wrong (like I initially did.)
