I used to think green and purple didn't go together either until someone posted a map here a while back with those colors and I realized that it's the shade that's important. So if you want purple roofs with green grass then I say go for it, I think it looks good. But I wear t-shirts and shorts 365, unless I go sledding with my nieces then I put on some jeans (they think I'm part dragon cuz I never get cold) or if I go golfing then I wear plaid shorts with Hawaiian shirts. So I may not be the best judge of style but at least I don't wear black socks with flip-flops...I'm not cool enough, yet, for that. I wonder if I can work in some paisley into a map....
