Luminous Inn
Five stops tuned to sit together without fighting — #8f281d ink anchors the set, #ffa496 opens it up, and #bb5648, #da7162, #e28779 cross the middle in a split-complementary arrangement. Luminous Inn suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
