Rosy Deck
Five stops tuned to sit together without fighting — #7c0b00 ink anchors the set, #f78875 opens it up, and #b23524, #d1533f, #d86c5a cross the middle in a monochromatic arrangement. Rosy Deck suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
