Jewel palette
Iris Delta
Five jewel stops with room to breathe — #3355c3 grounds, #5b82ee and #7ca1ff do the talking, #93b2ff softens, #bdd1ff 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.
