What is true of this colour, and of no other

23 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 only 25% of the chroma available at this lightness and hue — there is a far more vivid version of this colour inside sRGB.
As text on white it measures APCA Lc 21.9; on black, Lc -81.4. The sign is the polarity, which the WCAG ratio discards.

protanopia and deuteranopia and tritanopia shift it by ΔE00 7.1 and 7.8 and 24.2 — no red cone.
