#434b4f

A neutral that has no useful hue — it reads as a grey. It is mid — the hardest range to put text on, either colour struggles.

What is true of this colour, and of no other

  • 11 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 15% 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 90.4; on black, Lc -11.9. 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.
  • deuteranopia and tritanopia shift it by ΔE00 5.1 and 12.2 — no green cone.
