My room is too dark!

My room is too dark!



So last year I decided to paint my room purple. Now, a year later I REGRET IT. I'm not allowed to re-paint my room, so I was just wondering some ways to brighten it up!
A lighter comforter- what color, and so on. Also, I'm done with that posters wall-papering my walls, so what can I put on my walls instead?
