What is true of this colour, and of no other

  • 7 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 73.5; on black, Lc -28.2. 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 30.7 and 44.6 and 57.1 — no red cone.
