Great book and a million uses!
Format: Paperback
This works perfect to help create outfits that are perfectly coordinated! I grab one thing I really want to wear, find that color in the book, and then match everything else to the other colors. My daughter also uses it for paintings and art projects.

Like the other one (Vol 1) but different (Vol 2) with more.
Format: Paperback
Volume 2 continues the great color combinations of the 1st Volume, but the combinations are more complex, with more colors. There's even a section of art in the form of paintings, prints, woven work, etc. that you see on one page while on the opposite page is the breakdown of the colorations in bars with no image. What this does is show how the art works, and then how the combinations also work. Also more of the simplified 2 and 3 combinations that I think I prefer as more minimal. Again, these are ranged from light and airy to darkly saturated -and all curiously satisfying and worth study and trying them out. On the computer it's possible to match any tone or hue, so there's a path that only requires finding the right starting color then paying attention to the combination. Not that it's an end-all, but a beginning. Any of those can be shifted or modified with ease but it depends on how they fit a real-time application and not a formula. But the horizons have already been expanded so there's more, and even more.

Great book to help establish a palette for a software, web or art project
Format: Paperback
I love this book for helping me establish a color palette for art projects that I want a Japanese feel to. Also just generally good for getting inspiration for color palettes that just plain look good. I've always, since I can remember from my youth, felt drawn to the Japanese color combinations in kimono. fashion, origami paper and even toys. Maybe it's a consequence of growing up in Hawaii with all the Japanese influences I had -- or, as I suspect, it's just really good color application. This book helps me find the colors I want that go together the way I want. I use the examples in this book with a Color Muse to pick my digital color palette.
