#002233

A blue that is nearly neutral — the hue shows only against a true grey. It is dark — it carries white text and needs care with black.

What is true of this colour, and of no other

  • One other named colour sits within ΔE00 2 of it.
  • It sits exactly on the sRGB boundary: at this lightness and hue the gamut has nothing left, and a wider display would show a more colourful version of it.
  • As text on white it measures APCA Lc 103.1; 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 13.4 and 14.2 and 12.5 — no red cone.
