Dark Slate Gray — 11-step color scale

Dark Slate Gray (#2f4f4f) sits at 500, untouched. Every other step is Dark Slate Gray 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.#2f4f4f

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 Dark Slate Gray

Success, warning, error and the rest are derived from Dark Slate Gray 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.

Derived from #2f4f4f

Suggested	Protanopia	Deuteranopia	Tritanopia
success#504920	19.1	21.5	27.6
warning#653c33	10.9	16.5	40.0
error#613b4c	5.2	3.1	40.5
discovery#3a4769	12.7	10.9	5.1
info#18515c	6.0	6.3	3.6
neutral#495a5a	4.3	5.1	7.5

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 error suggestion starts out colliding with Dark Slate Gray under Deuteranopia — ΔE₀₀ 3.1, below the 11 threshold — so the engine shifts its hue within the error family until the pair pulls apart again.
