What is true of this colour, and of no other

  • 3 other named colours sit within ΔE00 2 of it.
  • It uses only 34% 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 96.6; on black, Lc 0.0. 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 10.6 and 17.3 — no red cone.
