Tropical palette
Flannel Reef
Five tropical stops with room to breathe — #004d4f grounds, #00797c and #329497 do the talking, #55a1a4 softens, #72bec0 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.
