Opera palette
Rustic Inn
Five opera stops with room to breathe — #00619f grounds, #308bd3 and #4fa7f1 do the talking, #6fb7f7 softens, #a3d3ff 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.
