Citrus Crater
Five petrichor stops with room to breathe — #004f51 grounds, #007b7d and #329698 do the talking, #56a4a5 softens, #73c0c1 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.
