What is true of this colour, and of no other

  • One other named colour sits within ΔE00 2 of it.
  • It uses 61% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 85.3; on black, Lc -16.8. 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 9.9 and 9.8 and 39.7 — no red cone.
