Here is one of my Bargello quilts in shades of purple....with white. It's a free pattern online. I did modify mine a bit, but it is the same pattern.

Bargello quilts are much easier than they look.
Hope this is helpful.
Oh, a Trip around the World might also be worth mentioning. Let me see if I can find one of those.
.....Hmmmm...looks like my Trip around the World is a bit out of focus. I don't know how to edit that once I have already posted. Sorry....
