Matcha palette
River Atelier
Five matcha stops with room to breathe — #5f3e00 grounds, #916200 and #ad7d2d do the talking, #b88e4f softens, #d5aa6b 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.
