Retro palette
Sable Orchard
Five retro stops with room to breathe — #722b00 grounds, #a25028 and #c06b43 do the talking, #c87f5e softens, #e79b79 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.
