Aurora palette
Sunset Square
Five aurora stops with room to breathe — #00475d grounds, #007191 and #308cad do the talking, #539ab6 softens, #6fb6d3 lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
