What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It uses 87% 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 79.8; on black, Lc -22.1. 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 31.6 and 40.3 and 50.0 — no red cone.
