Petrichor palette
Greige Foundry
Five petrichor stops with room to breathe — #5d4b00 grounds, #8b7200 and #a78d2f do the talking, #b39d53 softens, #cfba6f 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 for large text.
