I agree with everyone else. Both colors look great. And the colors in the squares could go with just about any background, not only blue or white. Since you're unhappy with both choices, maybe you should look at the room you want to put it in, and see what color feels best. light or dark, and go with that?
I thought my first quilt was ugly too, but I think it's because I struggled with it so much and really wanted it to turn out like the ones my friends made, with many years of experience under their belt.
I struggle with making color/pattern choices, and find that taking a black and white photo of the material samples helps me choose and organize it in my brain. I also take a picture of each quilt I finish, only 5 so far, and it helps me see what great strides I'm making.
And yes, I still think my first quilt was ugly, so I gave it to a local mission and I like to think that someone less fortunate than I loves it.
