Retro palette
Leafy Dune
Five retro stops with room to breathe — #6b5200 grounds, #9b7900 and #b79431 do the talking, #c3a558 softens, #e0c274 lifts. The split-complementary 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.
