Thanks everyone for the comments. The more I look at it, the more I don't like it. I think I'm going to mess around with it a bit more, I'm not liking the bold contrast between the two purples. I really want the four patch in the center to pop, and it's the light purple that is standing out.
Maybe I'll try with the dark purple outside like it currently is, then light green floral for the inside with the light purple being the chain, and the dark green for the center. That may give more balance than it has right now.
maybe I should give up on trying to use the purple for this quilt. I'm constrained by the yardage of have on hand. I really do like these four colors together, but this may not be the pattern for them.
