Petrichor palette
Quilted Library
Five petrichor stops with room to breathe — #4c3f00 grounds, #786500 and #93802b do the talking, #9f8f4c softens, #bbab68 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.
