Opera palette
Stone Meadow
Five opera stops with room to breathe — #006188 grounds, #008cc3 and #37a8e1 do the talking, #60b7e7 softens, #88d3ff 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 for large text.
