What is true of this colour, and of no other

31 other named colours sit within ΔE00 2 of it — this part of the space is crowded, and the names here are finer distinctions than most people make.
It uses almost none of the chroma available here: this is a grey with a trace of hue rather than a colour.
As text on white it measures APCA Lc 33.2; on black, Lc -69.5. The sign is the polarity, which the WCAG ratio discards.
Built into an eleven-step scale, 10 of the 10 adjacent pairs stay ΔE00 2 apart — see the ramp.
All three dichromacies see it as very nearly the same colour you do: its hue is not the part carrying its identity.
