Query: The Artist's Guide to Selecting Colors by Michael Wilcox

I purchased the 2001-2002 version of this book and quickly regretted it. Although he preaches quality for what he buys, his own material was so full of typos and errors that I can't trust the more technical data. Upon contacting the publisher I was told to send them a list of errors I found and don't return their poor quality book. Unfortunately, I am unable to proof read their book at my own expense and can only hope that they will someday practice what they preach. Buy only with extreme caution.
