Jealous Jellyfish

#bb0099

A magenta that is about as vivid as sRGB can show at this lightness. It is mid — the hardest range to put text on, either colour struggles.

What is true of this colour, and of no other

  • No other named colour in the set is within ΔE00 2 of it — it stands alone.
  • It sits exactly on the sRGB boundary: at this lightness and hue the gamut has nothing left, and a wider display would show a more colourful version of it.
  • As text on white it measures APCA Lc 76.9; on black, Lc -24.9. 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 28.0 and 26.5 and 69.4 — no red cone.
