Blue — 11-step color scale

Blue (#0000ff) sits at 500, untouched. Every other step is Blue 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.#0000ff

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 Blue

Success, warning, error and the rest are derived from Blue 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 #0000ff

Suggested	Protanopia	Deuteranopia	Tritanopia
success#006917	63.3	60.3	22.7
warning#a50007	59.9	66.1	50.9
error#9d0055	23.2	37.7	50.5
discovery#004eb6	9.6	10.6	9.5
info#00616e	20.7	19.2	17.8
neutral#73738c	19.1	22.5	16.9

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 discovery suggestion starts out colliding with Blue under Tritanopia — ΔE₀₀ 9.5, below the 11 threshold — so the engine shifts its hue within the discovery family until the pair pulls apart again.
