Lilac Deck
Five stops tuned to sit together without fighting — #86271d ink anchors the set, #f7a092 opens it up, and #b25447, #d06f61, #d98477 cross the middle in a split-complementary arrangement. Lilac Deck suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
