Mineral Dune
Five stops tuned to sit together without fighting — #7e262e ink anchors the set, #ee9d9d opens it up, and #a95255, #c76d6f, #d08182 cross the middle in a tetradic arrangement. Mineral Dune suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
