What is true of this colour, and of no other
- No other named colour in the set is within ΔE00 2 of it — it stands alone.
- It uses 48% of the chroma sRGB can show at this lightness and hue.
- As text on white it measures APCA Lc 86.4; on black, Lc -15.7. 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 9.3 and 8.9 and 46.1 — no red cone.
