Luminous Crater
Five jewel stops with room to breathe — #005a1f grounds, #008834 and #34a44f do the talking, #59b169 softens, #76ce84 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.
