Opera palette
Pumice Shrine
Five opera stops with room to breathe — #004878 grounds, #0070b6 and #308cd4 do the talking, #539bd9 softens, #6fb8f7 lifts. The complementary 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.
