Ocean palette
Lingering Library
Five ocean stops with room to breathe — #004b39 grounds, #00775d and #319277 do the talking, #539f87 softens, #70bba2 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.
