Opera palette
Vernal Prairie
Five opera stops with room to breathe — #6b2900 grounds, #a64400 and #c4602a do the talking, #cc754b softens, #eb9167 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.
