#474c50
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
- 20 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 10% 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 89.8; on black, Lc -12.4. 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.
- tritanopia shifts it by ΔE00 8.6 — no blue cone.
