Neon palette
Leaden Dune
Five neon stops with room to breathe — #005422 grounds, #257f41 and #449b5b do the talking, #61a771 softens, #7dc48c lifts. The tetradic 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.
