Surf palette
Luminous Delta
Five surf stops with room to breathe — #005d6c grounds, #00899e and #36a5ba do the talking, #5eb3c5 softens, #7bd0e2 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 for large text.
