Ocean palette
Restful Fjord
Five ocean stops with room to breathe — #007571 grounds, #24a29d and #4bbfb9 do the talking, #70ccc7 softens, #8ee9e4 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.
