#2b2c30
A neutral that has no useful hue — it reads as a grey. It is dark — it carries white text and needs care with black.

What is true of this colour, and of no other
- 9 other named colours sit within ΔE00 2 of it.
- It uses almost none of the chroma available here: this is a grey with a trace of hue rather than a colour.
- As text on white it measures APCA Lc 100.6; 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.
- All three dichromacies see it as very nearly the same colour you do: its hue is not the part carrying its identity.
