A cyan that is nearly neutral — the hue shows only against a true grey. It is dark — it carries white text and needs care with black.

What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It sits exactly on the sRGB boundary: at this lightness and hue the gamut has nothing left, and a wider display would show a more colourful version of it.
- As text on white it measures APCA Lc 99.6; 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.
- protanopia and deuteranopia and tritanopia shift it by ΔE00 16.6 and 17.3 and 14.9 — no red cone.
