Custom Nursery Design - Owls

I have been working on an Owl nursery for some time now (mostly just doing what I call "sketching" - namely, compiling different pictures and ideas that I find on the internet into a photoshop image). The initial colors were going to be Mint Green, Tangerine Orange, Bubblegum Pink, and Cerulean Blue, with maybe the occasional Ruby Red accent. The one problem with this is that it could only be for a girl. So I am working on a boy version, but I haven't quite nailed down the colors. Or I might come up with a gender-neutral version. I haven't decided yet. Any suggestions?(No, the sketch does not have the actual colors ... I was feeling lazy, I guess :) )
