So "black" as we use it is actually a misnomer, because it isn't truly black at all. In order for us to see it, it must reflect some small, tiny amount of light, which would make it definitively not black. Visible blackness (an oxymoron) reflects an amount of light so minimal that you perceive it as the absence of light entirely, when it is simply very, very, very dark grey.
I would say that 'greys' as a group are a curve approaching an asymptote -- black -- as they grow darker. So the "color" we call "black" is actually just the darkest possible grey we can create or perceive.

Man, stop spouting no sense. If you don't know physics, ophytalmology and the like.
you wouldn't ever see true black as that would mean nothing being transmitted. And we call a plethora of colors black. And who is to say black is a shade of grey. Really dark brow would look black to you as someone with brown hair can be Said to have Black hair because of the way you perceive it as a whole or a single hair.
a Blue wall when you turn of the Light turns black and by that a shade of grey because you in that situation would be incapable of seeing it is blue?
your eye have cells that see color and cells that see "greyscale" by light strength. Is a BW pic less colorfull because you took out information from it?
there is too much than the eye don't meet.
And it is no misnomer. In real life there is no true replication of straight line, circle, true black or white (the sun gives us an yellowish white. We call them those names because in pratical use that is what they are and they had that name before we understood them. Actually science uses the misnomer for simplicit. I would bet black was considered a color before newton explained dispersion of wavelength of visible light, discovered white was all and black none. And we took even more to understand only Black hole is true black (because not even Light escape it) because anything with energy will emit or reflect something. And the only real life straight I can remember is light path in vacumin total absence of gravity (never observed since true vaccum don't exist and no matter how faint gravity exist everywhere. So don't try to use absolute terms in confusion of theory and real life.
