Aquamarine — 11-step color scale

Aquamarine (#7fffd4) sits at 500, untouched. Every other step is Aquamarine composited over white or black at a decreasing opacity, so the whole ramp stays in one hue family instead of drifting toward another color at the ends.

Each step is the base composited over white or black at the opacity shown.#7fffd4

For text that needs to pass AA on white, 800, 900, 950 clear the 4.5:1 line. On a dark surface, 50, 100, 200, 300, 400, 500, 600, 700 do.

Semantic colors from Aquamarine

Success, warning, error and the rest are derived from Aquamarine itself, then checked so they stay distinguishable from the base — and from each other — under the three types of color blindness. The distance below is CIEDE2000 after each simulation.

CIEDE2000 distance from the base under each simulation. The lowest of the three decides, and a dot marks the ones that land under 11.

The info suggestion is the closest call: it clears the threshold under Tritanopia, but only reaches ΔE₀₀ 11.4, so it sits just above the 11 line rather than comfortably past it.
