Aurora palette
Dawn Oasis
Five aurora stops with room to breathe — #353da7 grounds, #5969d1 and #7285f0 do the talking, #8497f3 softens, #a5b6ff lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
