#dae6e9

A neutral that has no useful hue — it reads as a grey. It is very light — it works as a page background, not as text.

What is true of this colour, and of no other

  • 40 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 only 20% 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 13.6; on black, Lc -90.2. 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 5.8 and 6.2 and 12.9 — no red cone.
