Did not and do not believe that is reason some tankers are semi black, with my massive zero factual knowledge I boldly claim that bright neon pink/orange/green would be way more visible.
of course it matters against what you are trying to see something but against sea/sky black just cannot be easiest color to see.
Black is a staggeringly easy color to see at night if you are away from civilization. I've spent most of my life in fairly urban/suburban areas, so I never realized just how bright the night sky actually is until I joined the Army and went to Leonardwood for basic. We're doing a field training exercise, and during the first night of it they have us in formation for mail call. I wasn't expecting anything, so I let my attention wander, and I was absolutely
stunned when I looked up. I thought skies that looked like that were made using cameras with low shutter speeds or some other kind of long exposure.
Anyway, in many natural environments black stands out because it is significantly darker than the rest of the background. It works ok as night camouflage if you're stationary, but the second you move it completely fails. Sort of like how lions are a light, sandy brown in color, despite the fact that they do most of their hunting at night. Similarly, their prey doesn't use black camouflage, either. There are good reasons why black is a fairly rare color amongst vertebrates.
As for the tankers, I can't vouch for that way one or other, though I wager watching a dark blot on the horizon eating up and pooping out stars as it moves is a dead giveaway.
