An "all-blue" channel is an artifact of your television. Modern televisions put up a solid color rather than snow when they fail to detect a carrier wave on the chosen channel.

The mechanics don't really matter. It's still just as effective.

Ok, but the "all-blue channel" is just the TV turning all the lights blue when it can't find a signal. Why bring a TV into it if you can just put up blue lights?
