I wonder if she is color blind. She wears suits to work and always wears Jones New York so you buy the outfit all coordinated. Casually I see her in alot of blue and white or jeans and something. She did not pick the colors etc for her house, her hubby did.
I tried not to impose my picks on her except where it just clashed or where that FQ was definitely going to read dark not light in the quilt.
Starting simple with three colors or complementary would be a good start. The quilts that I have seen that are appealing which she picked are in fewer colors like 4P or 9P. Technically she does a good job of matching seams, being square and actual quilting.
