Straw Estuary
Five monochrome stops with room to breathe — #00446e grounds, #006caa and #2f87c7 do the talking, #5196cd softens, #6db3eb lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
