What is true of this colour, and of no other

  • No other named colour in the set is within ΔE00 2 of it — it stands alone.
  • It uses 82% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 88.5; on black, Lc -13.7. 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 21.2 and 22.1 and 24.3 — no red cone.
