That book on color was a revelation to me. I realized I'd choose to buy something because it was my color, and I may not have found it useful later. My DD is winter and I'm spring, so I stopped trying to dress her in my colors and made her cute little outfits in her colors. I now look at quilts with that bias (no pun intended.) Do I like that quilt design because the colors are my favorite, or is a pattern I really want to attempt?
