Opera palette
Twilit Cellar
Five opera stops with room to breathe — #6b2000 grounds, #a93800 and #c85529 do the talking, #cf6c4a softens, #ee8865 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.
