A blue that is nearly neutral — the hue shows only against a true grey. It is very dark — white text sits on it comfortably, black text does not.

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 45% of the chroma sRGB can show at this lightness and hue.
  • As text on white it measures APCA Lc 105.5; 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.
  • All three dichromacies see it as very nearly the same colour you do: its hue is not the part carrying its identity.
