Handy color book is "Color Index" by Jim Krause -- sure, it's a graphic arts book and gives formulations in CMYK and RGB, but will also give you a good sense of what colors look good together. And since Pantone (PMS = Pantone Matching System) is coming out with color books for use in fashion and decor, why not use another handy color book originally for graphc arts?
