A damn good question.

Don't ask, don't tell ?

They paint the black helicopters according to the sky color at the time of day/night they will be flying them. Thus, "black helicopters" only refers to helicopters flown at night. The terminology has fallen over into cloud helicopters, gray helicopters, blue helicopters, grayish helicopters, and the rare dusk helicopters. It really is a shame.

A REAL German would know the answer to this already.

No they can be darkish grey too, or very darkish blue. The important thing is they are completely silent and only visible to you and nobody else as when you wake up in the middle of the night to take a piss. They come in all sizes and you mostly can see them in the corner of your eye, but when you turn your head, they're gone, so you know they're quick. Sometimes you can't even see them, but you just *know* they're there, also they are telepathic.

Then you know it's a black helicopter!

Edit: They are piloted by greys or the mysterious men in black. Question: Are greys really greys if they wear black? I say yes.
