What is true of this colour, and of no other

  • 9 other named colours sit within ΔE00 2 of it.
  • It uses 92% 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 51.1; on black, Lc -50.9. 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 8.5 and 8.3 and 44.4 — no red cone.
