I think that some of the new color combinations that you see in bedding now would be really pretty. My favorite is the chocolate brown and light blues that you can find. You could find a blue that would be soft on the walls and then as others suggested paint the wall behine the bed brown, this would draw the eye into the room. I say don't be afraid of color, sometimes color helps to make a small room feel bigger. I always say it's only paint, if you don't like it paint it again.
