Opera palette
Butter Atelier
Five opera stops with room to breathe — #004977 grounds, #1772b0 and #3a8dcd do the talking, #5a9dd4 softens, #76b9f2 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 as a text pair.
