Opera palette
Sorrel Prairie
Five opera stops with room to breathe — #004765 grounds, #00709d and #308bba do the talking, #529ac2 softens, #6fb6df 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.
