Marble Alley
Five stops tuned to sit together without fighting — #9c0031 ink anchors the set, #ffa4aa opens it up, and #cd4157, #ed5f71, #f37a86 cross the middle in a split-complementary arrangement. Marble Alley suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
