I'd like to paint the wall around the screen and ceiling a dark color - likely black to absorb excess light. What type of paint do you recommend. I assume a flat finish?
Keep in mind that some people think that too much black makes the room look "gloomy" when not actually watching a movie. Many people go with a dark color, but not necessarily black (i.e. burgundy, dark green). This makes the room look brighter when the lights are on, but then it still looks black when watching a movie.
