I guess I do have an "eye" for color...that is my favorite part of making a quilt. Sometimes it can help to find a fabric that you love the colors in, and use that fabric as a guide to pick fabrics that go together. You can then either take away the fabric you started with and have a group of fabrics that works together, or you can use the fabric that you started with-it usually makes a great border. There are many books on color theories, and maybe you have a shop in your area that teaches a class on color. I do think that the more you do it does get easier. Some people have an easier time if they only have to pick out 3-5 colors. I have an easier time when I pick lots of colors...the more the better.
