I don't know. I still like the light green. The burgundy definitely makes all the burgundy jump out of the fabric, but, I agree, that burgundy is dull. The gold, you lose some of the blocks in there. Too close to the same color. You didn't put dark green back up there so can't comment on that.
I still like the light green. But, this is YOUR quilt, and you need to pick what best suits you. What color do you like?
