What is true of this colour, and of no other
- 7 other named colours sit within ΔE00 2 of it.
- It uses only 8% 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 81.2; on black, Lc -20.6. 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.
- tritanopia shifts it by ΔE00 5.4 — no blue cone.
