Luminous Oasis
Five jewel stops with room to breathe — #007355 grounds, #00a27a and #3cbf95 do the talking, #67cba7 softens, #85e9c3 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.
