Nursery color scheme

Crystal

I posted a little while ago asking for a way to make a girlish nursery around this crib, but I'm still trying to think of what colors to paint the walls. I want something bright to open the room up a little but I don't want anything crazy vivid since it will be a bedroom.

I'm also thinking I might want to paint 3 walls and the ceiling one color and have an accent wall.

Any suggestions?
