What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It uses only 32% of the chroma available at this lightness and hue — there is a far more vivid version of this colour inside sRGB.
- As text on white it measures APCA Lc 70.6; on black, Lc -31.1. 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 8.2 and 8.4 and 28.7 — no red cone.
