Autumn palette
Distant Harbor
Five stops tuned to sit together without fighting — #a20011 ink anchors the set, #ffaaa0 opens it up, and #d4413c, #f45f57, #fa7b71 cross the middle in a split-complementary arrangement. Distant Harbor suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
