I painted my room purple when I was thirteen. Let me tell you a secret: It was a very bad idea. lol.
It's a really annoying color and doesn't match anything at all. I'm saving up for this comforter and sheets:

And I'm going to paint my room (Most likely the room I get when I move out.) That red and white. I'm trying to decide if I want to paint it white and paint those kinds of flowers stemming from the carpet or red and have white flowers. Then I'll have black and white photos in frames.
Just make sure you're going to like it in the future. Mine feels really childish and it needs to be more sophisticated for my tastes right now. I wouldn't go for too bright of colors, but do whatever you please! Just giving out some ideas, good luck!
Maybe a black and white mickey room? They have a cute comforter on the disney shopping website.
