Monochrome palette
Rocky Shrine
Five stops tuned to sit together without fighting — #004951 ink anchors the set, #70b9c3 opens it up, and #007480, #318f9b, #539ca7 cross the middle in a split-complementary arrangement. Rocky Shrine suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
