#0c121b
A neutral that has no useful hue — it reads as a 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
- One other named colour sits within ΔE00 2 of it.
- It uses only 31% 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 105.3; 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.
- tritanopia shifts it by ΔE00 7.6 — no blue cone.
