What is true of this colour, and of no other

  • 24 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 29% 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 15.4; on black, Lc -88.3. The sign is the polarity, which the WCAG ratio discards.
  • Built into an eleven-step scale, 10 of the 10 adjacent pairs stay ΔE00 2 apart — see the ramp.
  • protanopia and deuteranopia and tritanopia shift it by ΔE00 10.0 and 10.8 and 16.3 — no red cone.
