Do you ever go to a quilt show and just enjoy looking at quilts from a distance, forget the details for a moment, enjoy the color! Do you get that same sense of excitement when you walk into a quilt store, do some fabrics "speak to you"? Let yourself go and enjoy color, don't over analyze. I think the difference between those who say they enjoy picking colors and those who don't is self-confidence.
Let yourself be a kid again. There are too many color police out there that will stifle you. You will get everyone else's reactions but not your own and you owe it to yourself to see what pleases you.
