Steel Blue — 11-step color scale

Steel Blue (#4682b4) sits at 500, untouched. Every other step is Steel 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.#4682b4

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

Semantic colors from Steel Blue

Success, warning, error and the rest are derived from Steel 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 #4682b4

Suggested	Protanopia	Deuteranopia	Tritanopia
success#618a4d	40.3	39.7	11.2
warning#a86d3d	41.2	44.3	47.3
error#a96383	11.9	17.7	56.3

info#008b87	16.0	12.2	4.6
neutral#707e89	12.6	13.3	13.4

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 Steel Blue under Deuteranopia — ΔE₀₀ 1.3, below the 11 threshold — so the engine shifts its hue within the discovery family until the pair pulls apart again.
