Here's what I decided on...BettyGee called it with her suggestion of red. We tried everything and the purple in a lighter shade looked good too, but too feminine. The orangey colors made it look too Harley Davidson or Halloween. Tried various grays and greens...no spark, but I really like the red. Even though the solid black looked great, I just decided I didn't want to go there with a quilt that was going to see a lot of actual use. Got enough for sashing and I'll sash it with black too. and probably a small strip of one of the contrasting primaries.
