Seaside Fjord
Five jewel stops with room to breathe — #00506e grounds, #1f7aa1 and #4195be do the talking, #60a4c6 softens, #7cc0e4 lifts. The split-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.
