The photographs in this book are great. As you might imagine with a book by this title there is a bold use of color. The style is modern, but will probably stand the test of time. I like the way the book is sectioned into chapters that fit a particular mood you might want to create (e.g. colors for fantasy). Also, there are general decorating tips scattered throughout the book.
The color choice quiz. Listed from A-Z all the emotions/moods you could ask for. You choose which emotions/moods you want to promote in a room. Then, you look at the color choice key to see which color matches those emotions/moods.
After buying the book and looking at it more carefully, I realized something...it has some of the same pictures as a book which I also own titled Color Healing Home by Katherine Sorrell. For example, check out pg. 27 of Color Healing and pg.63 of Color Therapy.
How to differentiate between the two: Color Therapy focuses more on how to promote moods. It lists moods and tells you what colors enhance that mood. Color Healing Home gives you more choices of color hue. They have a page for each hue and then tell you what moods each of these hues promote. You say tomatoe and I say tomato. I decided to keep both books, but I am a color junkie.
What makes Color Therapy standout is the color choice quiz. If that is something that interests you, I would recommend this book. Otherwise, it is a coin toss between Color Therapy and Color Healing, and other books with bold uses of color.
