What is true of this colour, and of no other

  • It uses only 19% 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 34.0; on black, Lc -68.6. The sign is the polarity, which the WCAG ratio discards.
