Knight’s Armour
#5c5d5d
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
- 15 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 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 82.7; on black, Lc -19.2. 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.
