Ocean palette
Opal Bluff
Five ocean stops with room to breathe — #006666 grounds, #009494 and #39b0b0 do the talking, #62bdbd softens, #7fdbda 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.
