Ocean palette
Granite Junction
Five ocean stops with room to breathe — #004854 grounds, #007284 and #308d9f do the talking, #539baa softens, #6fb7c7 lifts. The tetradic 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.
