Petrichor palette
Topaz Delta
Five petrichor stops with room to breathe — #6d5c00 grounds, #9c8400 and #b8a033 do the talking, #c4b05b softens, #e1cd78 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 for large text.
