Polar Lighthouse
Five aurora stops with room to breathe — #004e53 grounds, #007a80 and #32959b do the talking, #56a3a7 softens, #72bfc4 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.
