I made a batik quilt one time and the same thing happened with some yellow fabric after I was done with the top. I couldn't stand it so I mixed up a little brown fabric paint diluted it tremendously and painted those fabric pieces. It muted it enough that it blended well and I was ok with it. Be sure to iron after it dries to "set" it. In your case I think you mightd try a little orange paint instead of brown or a mix of both. Your quilt is beautiful.
