Black bedspread

Black is always nice in combination with white. If you have white sheets, and would like a stylish, modern look to your bedroom without having to make major changes to the decor, a black bedspread is a good choice. Be aware, however that even if your bedroom has white walls, black will absorb light and darken the room.
