Marigold Square
Five jewel stops with room to breathe — #005672 grounds, #0081a9 and #349dc6 do the talking, #5aabce softens, #77c8ec 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 for large text.
