Aurora palette
Marble Foundry
Five aurora stops with room to breathe — #00485c grounds, #007290 and #308dac do the talking, #539bb6 softens, #6fb7d3 lifts. The analogous bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
