Surf palette
Topaz Heath
Five surf stops with room to breathe — #004a4b grounds, #007577 and #319092 do the talking, #539d9e softens, #70babb 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.
