Sienna — 11-step color scale

Sienna (#a0522d) sits at 500, untouched. Every other step is Sienna 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.#a0522d

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

Semantic colors from Sienna

Success, warning, error and the rest are derived from Sienna 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 warning suggestion starts out colliding with Sienna under Tritanopia — ΔE₀₀ 1.7, below the 11 threshold — so the engine shifts its hue within the warning family until the pair pulls apart again.
