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 75% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 89.1; on black, Lc -13.2. 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 7.3 and 7.5 and 11.9 — no red cone.
