Aurora palette
Thistled Bookshop
Five aurora stops with room to breathe — #3c439b grounds, #616ec5 and #7a8ae3 do the talking, #8c9be8 softens, #aab8ff lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
