I will add, it does get easier. My problem is I have two natures. One wants all the brightest, gaudiest fabrics possible. The other wants the calm pastels. The only think I am sure of is that I don't like colors that are grayed. I want clear colors. Just get to know your likes and dislikes.
Another trick I learned in my color class was to pick a favorite object or picture for inspiration. Look at the colors. I picked my grandmother's candy dish for my inspiration. It was one of the easiest quilts to pick fabrics for and it's one of my very favorites.
