I would pick one of the colors and add white. I would probably go with turquoise. That is probably because I have a turquoise and white quilt and really like it.
Since you asked what colors and got an answer, I would do something in one or both colors.
I am going to see if I can find a picture of it, so you can see the combination. It make a very striking quilt. Just in case it "rings your chimes."
