What is true of this colour, and of no other
- 2 other named colours sit within ΔE00 2 of it.
- It uses 93% of the chroma sRGB can show at this lightness and hue — close enough to the boundary that a wider display would show it slightly more vividly.
- As text on white it measures APCA Lc 66.5; on black, Lc -35.1. 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 20.6 and 20.8 and 44.7 — no red cone.
