Jewel palette
Cumin Beacon
Five jewel stops with room to breathe — #2f36b3 grounds, #5165de and #6982fd do the talking, #7d95fe softens, #a2b6ff 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.
