Aurora palette
Harbor Prairie
Five aurora stops with room to breathe — #004b5b grounds, #00768d and #3191a9 do the talking, #559fb3 softens, #71bbd0 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.
