Ocean palette
Sienna Gallery
Five ocean stops with room to breathe — #00736d grounds, #00a19a and #3cbeb6 do the talking, #68cbc4 softens, #86e8e1 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.
