You know what, you sent me into dream mode. Let me share what I'd dream of doing, and you pick whatever part of it that interests you! :)
I'd so totally experiment with colors! Walls and comforter are comfortably neutral and beige. Excellent. Gives us some room to play with.
If the room is quite large, open and with a lot of natural light, then I'd go with a bold color. Something like a deep cherry, or a charcoal gray. Or better, hit the metallic shades - copper, pewter, bronze.
If the room is relatively closed and cozier, then I'd go with good old stark white. White always gives a roomy feel. Maybe add some cool kind of door knobs or handles on the draw, to give it a creative touch!
Actually, if I had the opportunity, I'd change my curtains to kind of highlight the new color (since the walls and bedding will remain the same). For eg., if I painted the dresser and nightstand a charcoal gray, I'd pick white curtains with lemon yellow, gray and green things - flowers maybe, or some kind of geometric print.
If curtains are out of question, then perhaps I'd add a couple of pictures with frame colors to match the new colors of the dresser. Or maybe change a cushion or pillow covers. Just something in addition to the dresser and nightstand, to highlight the efforts and ideas! :)
Hope you have fun doing it all!
