LE NOIR "GLAMOUR"
Why not consider adding a little drama in your space. High gloss black paint - à la David Hicks circa 1960's will do it every time. The high gloss screams flourish while the black shouts mystery. Of course the walls need to be PER.FECT! not a bump, not a dent, not a scratch, and the result is much more successful if you choose a room that is on the dark side of the house to start with. But other than that, what an easy fix.
