It uses only 30% 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 9.1; on black, Lc -95.1. The sign is the polarity, which the WCAG ratio discards.

protanopia and deuteranopia and tritanopia shift it by ΔE00 7.1 and 7.3 and 21.9 — no red cone.
