What is true of this colour, and of no other

- It uses only 27% 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 105.9; on black, Lc 0.0. The sign is the polarity, which the WCAG ratio discards.
