Add accessories to your room in daring colors to break up the dark‐colored. Don't clutter the room too much, but using a sizable brightly‐colored painting or a high, bright vase filled with bouquets can bring an entire whole lot of color into the room.
Look for bits that supplement your theme. For a living room, it's best to avoid anything too controversial ‐ scenery and black‐and‐white images are fine, but erotica and dead family pets are out, unless you really wanna make a declaration (or put some things away when your mother‐in‐law comes over).
Change out your draperies. If you have dark and heavy draperies, consider purchasing sheer curtains or curtains made out of a lighter weight fabric.
