What is true of this colour, and of no other
- One other named colour sits within ΔE00 2 of it.
- It uses 68% of the chroma sRGB can show at this lightness and hue.
- As text on white it measures APCA Lc 76.2; on black, Lc -25.5. 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.
- All three dichromacies see it as very nearly the same colour you do: its hue is not the part carrying its identity.
