What is true of this colour, and of no other

  • 55 other named colours sit within ΔE00 2 of it — this part of the space is crowded, and the names here are finer distinctions than most people make.
  • It uses 61% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 14.6; on black, Lc -89.2. The sign is the polarity, which the WCAG ratio discards.

  • protanopia and deuteranopia and tritanopia shift it by ΔE00 8.3 and 8.4 and 20.8 — no red cone.
