Aurora palette
Birch Cellar
Five aurora stops with room to breathe — #004755 grounds, #007187 and #308ca3 do the talking, #529aad softens, #6eb6ca lifts. The split-complementary bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
