What is true of this colour, and of no other
- 37 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 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 19.3; on black, Lc -84.2. 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.
- protanopia and deuteranopia and tritanopia shift it by ΔE00 23.2 and 22.5 and 55.2 — no red cone.

White text
1.42:1 — fails AA
Black text
14.83:1 — passes AA
Black text is the better of the two at14.83:1. That is enough for body text.
As text on white, it needs to change
#198a00 is the nearest colour of the same hue that passes AA on white, at 4.50:1. Only the lightness moved, and some saturation was given up to stay inside sRGB.
