What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It uses only 16% 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 87.9; on black, Lc -14.3. 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 5.2 and 5.6 and 14.1 — no red cone.
