What is true of this colour, and of no other
- 5 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 56.7; on black, Lc -45.0. 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 8.0 — no blue cone.
