What is true of this colour, and of no other

It uses only 10% 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 38.0; on black, Lc -64.4. The sign is the polarity, which the WCAG ratio discards.

protanopia and deuteranopia and tritanopia shift it by ΔE00 5.5 and 5.9 and 15.9 — no red cone.
