You gov't types are only saying that because you don't want to admit to the black helicopters....
I'm aware that "denial is proof", but I haven't worked for the govt in any capacity in many years and back then I was just an innocent, boring commo geek. If ya need help with a SINCGARS or a network, I'm your dude. Now, on the other hand, Leatherneck IS one of 'em nefarious govt folks. Ask him about his black ops missions involving a coffee pot, a bottle of vodka, a TPS report, and three cute Pentagon secretaries.
But seriously, black is a bad color if you're trying to hide. It's too dark, and thus easy to spot. Lighter colors blend in better and are much harder to spot. Some spy aircraft and UAV's actually have lights on the bottom to make them harder to spot. Simple wiring, you literally just need a light dependent resistor, a control relay and a light.
