What is true of this colour, and of no other

  • 32 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 37% 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 19.1; on black, Lc -84.4. 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 5.9 and 6.3 and 11.5 — no red cone.
