I did. It has a LOT of information about color, color schemes & tones. It's one of the better color classes I've taken (I gave it 4/5 stars) but she doesn't use any neutral in her quilts at all. I wrote "I would much rather buy some grey, taupe, white, black, cream & yellow fabrics to help draw attention to the beautiful colors than to follow the suggestion of flipping dyed* fabrics over to the backside". I know there are plenty of quilters that like using the backside of printed fabrics, but I almost never do. I just don't like that look. If you do, you'll love this class because she talks about that technique a lot. Still, even though I only like one of her no-neutrals quilts, I was definitely helped by this class.
*I wrote "dyed", but I meant printed.
