A red that is about as vivid as sRGB can show at this lightness. It is mid — the hardest range to put text on, either colour struggles.

What is true of this colour, and of no other
- 18 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 70.8; on black, Lc -30.9. 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 42.5 and 45.8 and 50.5 — no red cone.
