What is true of this colour, and of no other

  • 8 other named colours sit within ΔE00 2 of it.
  • It uses only 6% 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 89.0; on black, Lc -13.3. 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.
  • tritanopia shifts it by ΔE00 15.7 — no blue cone.
