How to brighten up a dark room
Paint the ceiling white.
If the room's ceiling is painted a dark color, or has dark wooden beams, it is probably casting a pall over the entire room. Buy a can or two of white paint and give the ceiling a fresh coat.
The bright white will reflect light instead of absorbing it, and you'll be amazed at what a difference it makes. If you prefer to use color instead of plain white, try a pale yellow, mint or cream.
