What is true of this colour, and of no other
- 10 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 65% of the chroma sRGB can show at this lightness and hue.
- As text on white it measures APCA Lc 85.1; on black, Lc -16.9. 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 28.4 and 31.8 and 38.0 — no red cone.
