Jewel palette
Cream Delta
Five jewel stops with room to breathe — #033c7b grounds, #3465a4 and #4e80c1 do the talking, #658fc8 softens, #80ace5 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 as a text pair.
