What is true of this colour, and of no other
- 5 other named colours sit within ΔE00 2 of it.
- It uses only 24% 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 91.0; on black, Lc -11.4. 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.
