I think you should just leave the colors as she likes them. My daughter picked out fabrics for a quilt my mom made her. She picked out 4 colors that don't go with each other at all. It hurts my eyes to look at the quilt...but it is one of her favorite quilts(the only one she likes better is the one she picked out when she was 1 year old). She uses it all the time and is very happy with it. We each have our own styles and likes and dislikes. There might be something that triggers good memories with the fabric she picked out. we'll never know.
