Bitter Brook
Five midcentury stops with room to breathe — #006f69 grounds, #009d95 and #3bb9b1 do the talking, #66c7bf softens, #84e4dc 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.
