Chalky Mesa
Five stops tuned to sit together without fighting — #253a7d ink anchors the set, #91aae8 opens it up, and #4a63a6, #637ec3, #768eca cross the middle in a split-complementary arrangement. Chalky Mesa suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
