Thinking about this, I realized the darker the color the blacker it will become once the room light goes down, therefore go with Eric's grey or black and save the cash. But, the speakers are large enough to make a statement in the living room so go with something unique!
I looked up the Bentley home page to get their car's exterior colors....it's a good site. Then to Home Depot to get paint samples. That picture of the BMW grey was nice....I just need something to match the colors at home.
