PERSONALLY, I would go with either white, off-white, or beige. I like white, off-white, or beige colored walls, with a nice wallpaper border to add personal taste to the room. I'm actually planning on getting a nice border for my room. My walls are off-white, and I like it that way. I usually don't like 'colored walls'. There are exceptions, of course, but I 'usually' don't like bright or different colored walls. I like murals sometimes...if they're really nice, but not one plain color. If its going to be plain, it has to be white, off-white, or beige for me. That way, you can also have any colored furniture, bedding, rugs, etc. and it will all match. If you paint your room a certain color and later get new furniture or rugs or bedding, etc. you're going to have to paint it all over again or it won't look good.
