I like all the suggestions listed and have another book suggestion also: Jinny Beyer's Color Confidence for Quilters. In her book she also has little color swatches that help with subtle color differences that are very helpful so you can try different ones together or even take them shopping.
And I have to say I love the Bargello! Made from donated fabrics? Wow. Very impressive!!! I've never done one but want to. I wish I could have you sit next to me and guide me along. This one is just perfect!
