A neutral that has no useful hue — it reads as a grey. It is dark — it carries white text and needs care with black.

What is true of this colour, and of no other

  • No other named colour in the set is within ΔE00 2 of it — it stands alone.
  • It uses only 35% of the chroma available at this lightness and hue — there is a far more vivid version of this colour inside sRGB.
  • As text on white it measures APCA Lc 104.8; on black, Lc 0.0. 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 11.3 and 12.8 and 18.5 — no red cone.
