Sumi palette
Yuzu Ridge
Five sumi stops with room to breathe — #761600 grounds, #ac3920 and #cb563c do the talking, #d26e57 softens, #f18972 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.
