Retro palette
Kelp Ridge
Five retro stops with room to breathe — #831616 grounds, #af4840 and #ce635a do the talking, #d57a70 softens, #f4968b 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.
