Acid palette
Punchy Hollow
Five acid stops with room to breathe — #004b44 grounds, #00776c and #319286 do the talking, #549f95 softens, #70bbb0 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 as a text pair.
