Emerald Harbor
Five monochrome stops with room to breathe — #22621e grounds, #4f8b4a and #6aa764 do the talking, #80b47b softens, #9cd197 lifts. The split-complementary bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
