Aurora palette
Sunbaked Delta
Five aurora stops with room to breathe — #004d4f grounds, #00797b and #329496 do the talking, #55a1a3 softens, #72bebf lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
