What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It uses 65% of the chroma sRGB can show at this lightness and hue.
- As text on white it measures APCA Lc 102.8; on black, Lc 0.0. 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 10.7 and 11.7 and 18.7 — no red cone.
