Opera palette
Crimson Lane
Five opera stops with room to breathe — #005a89 grounds, #3884b6 and #55a0d3 do the talking, #71afdb softens, #8dccf9 lifts. The triadic 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.
