Aurora palette
Cozy Fen
Five aurora stops with room to breathe — #005e68 grounds, #008b98 and #37a7b4 do the talking, #5eb4bf softens, #7bd1dd lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
