Opera palette
Tidal Bluff
Five opera stops with room to breathe — #7e2400 grounds, #b44621 and #d3623e do the talking, #da795b softens, #f99576 lifts. The analogous bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
