Opera palette
Kiln Heath
Five opera stops with room to breathe — #00466b grounds, #006fa5 and #308ac2 do the talking, #5299c9 softens, #6eb5e7 lifts. The analogous 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.
