I absolutely love this book...I bought it for myself because I struggled with coordinating colors or just trusting what I thought looked good and have found it extremely helpful to me, esp when I want something to look just so or I'm trying to create a particular feel.
She's asked for your help so I think it gives you some freedom to lovingly share your knowledge about color, scale, and hue!
