What is true of this colour, and of no other
- 4 other named colours sit within ΔE00 2 of it.
- It uses only 35% 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 78.3; on black, Lc -23.5. 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 17.7 and 18.6 and 45.5 — no red cone.
