Opera palette
Emerald Pagoda
Five opera stops with room to breathe — #6c2000 grounds, #a43f17 and #c25b35 do the talking, #ca7152 softens, #e98c6d 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.
