What is the best color to paint behind a High Defintion tv mounted on the wall?
The best thing to have back there is a little bit of light that doesn’t fall on the front screen (therefore washing out the image). If the lights are off in the room, then a small light behind the TV is helpful. This lightness helps to increase the perceived contrast of the display over what you see in a completely darkened room. If the room is illuminated, a light grey is probably the best choice. Light, but not too bright like a white, and neutral to not bias the color perception of the display.
