Off the wheel, Off the charts. What sort of creativity could be happening for you if color was a more open question?...Eight very concise chapters.
From the introduction:
"Despite the many benefits to be had from a thorough study of hue, value and chroma the system has become too common a fallback for artists. Since the tendency with a standard fallback is a more or less generic result, it seems artistically savvy not to trust your nest egg to one basket. Particularly for the times when your projects are calling for something exceptional."
