Jewel palette
Butter Abbey
Five jewel stops with room to breathe — #263e88 grounds, #4c67b1 and #6582cf do the talking, #7993d4 softens, #93aff3 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.
