There are some websites that let you look at how colors look together. There is one that shows you all the colors in a picture. Find a focus fabric and use coordinating fabrics from the little colored circles in the selvage. Ask for help picking colors in your LQS- or here! I hope this helps, keep at it. I had no idea how to choose colors for a quilt when I first started about fifteen years ago. Now I am really into scrappy quilts and buy what pleases me.
