This is a book of color palettes with some brief explanations about color psychology as it relates to marketing.
I am disappointed in the lack of information in the front of the book about what color is, how we see it, and any explanation at all about the different color wheels used by designers. Looking at the color palettes in the back of the book, cyan and magenta are included but the CMY wheel is not presented in the book - only the RYB wheel is shown. There's no cyan or magenta present in the RYB wheel, so if you follow the advice of the book (which clearly uses the CMY wheel for finding color harmony), you'll not be able to make the same color combinations that are shown.
