Opal Lagoon
Five ocean stops with room to breathe — #005371 grounds, #007ea9 and #349ac6 do the talking, #59a8ce softens, #76c5ec lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
