What is true of this colour, and of no other

  • 13 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 79% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 72.9; on black, Lc -28.7. 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 35.4 and 41.3 and 48.3 — no red cone.
