What is true of this colour, and of no other

  • 15 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 53% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 11.4; on black, Lc -92.6. 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 5.4 and 5.8 and 8.9 — no red cone.
