What is true of this colour, and of no other

  • 4 other named colours sit within ΔE00 2 of it.
  • It uses 96% of the chroma sRGB can show at this lightness and hue — close enough to the boundary that a wider display would show it slightly more vividly.
  • As text on white it measures APCA Lc 70.2; on black, Lc -31.5. 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 15.2 and 14.7 and 55.6 — no red cone.
