Here is my bathroom after:
The back wall is a mint green. I was going to do all the walls this color, but after doing the one, I realized the bathroom was going to look like the inside of a toothpaste tube if I continued with that plan. So I did the rest of the walls yellow, the ceiling and shelving blue, and the trim "fuchsia fizz".
Not sure if this is an improvement or not, but it sure is "different". Hey, if I get sick of it, I'll just paint it again.
