Might be old school but black is the best camo at night, heck even in daylight black fades in. No disrespect for those that want to add a paint job to there rifles, basic black works fine for me.
its pretty well established that black stands out the worst over all earth-tone colors, even at night. this is why the military has completely dropped black from camo applications... it's not on the boots, its not in the uniforms, and they've finally just authorized the painting of black rifles. because black is worthless for camo.
