Marble Dune
Five stops tuned to sit together without fighting — #00636f ink anchors the set, #7ed7e6 opens it up, and #0090a1, #38acbd, #61bac8 cross the middle in a split-complementary arrangement. Marble Dune suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
