Just for fun - what are your favorite bathroom colors?

The bathroom is a simple galley with 2 sinks, a toilet and a tub/shower combo. It's pretty narrow, It will be my bathroom that I'll be sharing with our toddler daughter.

I'd like it to be fun, maybe whimsical but still not too "kid" so I enjoy being in there, too. IE: I don't want the theme to be rubber duckies.
