Plum Porch
Five stops tuned to sit together without fighting — #ad1600 ink anchors the set, #ffb9ac opens it up, and #dc503b, #fc6d57, #ff8a75 cross the middle in a analogous arrangement. Plum Porch suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
