Petrichor palette
Powdery Ridge
Five petrichor stops with room to breathe — #443f00 grounds, #6d6600 and #87812b do the talking, #95904b softens, #b0ab67 lifts. The triadic 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.
