i love the Color Harmony books and own several of them. This entry, in a convenient size condenses the schemes in the first two books (the basis for all the others) and presents it in a way that is really helpful.
The heart of the book are the color schemes, grouped first by mood and then by type of sceme. After noting the central color for each mood, there are 59 schemes with two or three colors, in all the color schemes. Each scheme is shown using the colors from the 100= pallette that is the basis for the work.
Each of those colors is shown first on the color wheel and then in a numbered swatch. Those numbers appear under the swatch whenever it is used. There are 8 shades for each color and the ten shades in the standard grey scale.
Using these colors is made easier by several tools in the back of the book. First there is a table listing all the colors, with small swatches and their process (CYMK) numbers. Next, the swatches are shown with the CYMK numbers next to them. On facing pages are color cards that could, i think, be cut out and used for matching.
This is a gloriously useful book for anyone, in any medium who works with color.
