Brown — 11-step color scale

Brown (#a52a2a) sits at 500, untouched. Every other step is Brown 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.#a52a2a

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

Semantic colors from Brown

Success, warning, error and the rest are derived from Brown 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 Brown under Deuteranopia — ΔE₀₀ 4.6, below the 11 threshold — so the engine shifts its hue within the warning family until the pair pulls apart again.
