You might want to look for an *inspiration piece*, maybe a picture or poster that has colors in it that appeal to you. Inasmuch as this is your bedroom, do you think you will be getting different bedding? You can start by finding some which has several colors in it and take your cues from that.

One thing I would like to recommend is to be prepared to put on two coats of paint. My husband just painted my office and I knew it needed a second coat but he was tired and wanted the one coat to suffice. Now I see all kinds of places where I can see the previous color (white) peeking through.
