Ocean palette
Pewter Inn
Five ocean stops with room to breathe — #00455b grounds, #006f90 and #308aac do the talking, #5298b5 softens, #6eb4d2 lifts. The analogous bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
