What is true of this colour, and of no other

  • One other named colour sits within ΔE00 2 of it.
  • It uses only 23% 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 54.9; on black, Lc -46.9. 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 5.8 and 6.0 and 8.1 — no red cone.
