1 Black Wall? Eureka!

Many years ago I was out driving to get dinner and I decided to try a different route to avoid traffic. This new street had one house that stood out because it was a nice house in a poor neighborhood and as I drove past it I saw through the window that it had one black wall. I thought "that's a really interesting interior design choice." Well I thought it over for a few YEARS and just today as I was eating peanuts I realized that it might be a way to reduce glare on the TV. By the way, playing Resident Evil games with a glare on the TV means you can't see jack shit. Anyway, one black wall sounds really neat and I'm inclined to try it.
