I love color and often get positive comments on the combos I use, however, I rather doubt that I am naturally better at it than you are. I use the colors I like to see,
I use Quilt Pro, although any quilt software would be good. Try 'plugging in' various colors until you see what you like. My DH is partly color blind, but this method works with him.
Select a main fabric you like at the LQS. Take other fabrics and put them underneath, so you see them along the edge. Keep changing until you have a combo that works for you. Then look for the pattern you want to use.
