It sounds to me that your problem is not being able to put colors together. I think you can solve your problem permanently for about $20, if you take Joen Wolfram's class on color theory on Craftsy.com. She's an excellent teacher (I have had a number of her classes in person) and really knows what she is doing with color. I've learned a lot from her, always use a color wheel, and have had many compliments on the colors I put together. Craftsy has sales on classes from time to time. Joen has several tools and books for sale for determining color combinations; most quilt shops carry them.
There's an out-of-print book by Jenny Beyer called Color Confidence that is also very helpful.
