Opera palette
Frosty Delta
Five opera stops with room to breathe — #004a7c grounds, #0072bb and #308ed9 do the talking, #549dde softens, #70bafc lifts. The monochromatic 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.
