Acid palette
Satin Dune
Five acid stops with room to breathe — #004c5e grounds, #007691 and #3191ad do the talking, #559fb7 softens, #71bbd4 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.
