We went with black as it really helps in camoflaging the overflow, heater, PHs, and skimmer box.
We got a sheet of the black on one side, blue on the other background material and gave each a test-run by tacking it on the back of the tank for a few days. Wife liked the color of the blue (Although it was a little too light, I think a really dark blue would have looked better) but agreed that the black added a bit more depth and helped hide all the gear. Unless the full white lights are on, everything's virtually invisible, and even then is less obtrusive.
