Sandy Square
Five disco stops with room to breathe — #003e74 grounds, #0064b5 and #2c80d3 do the talking, #4e90d7 softens, #69acf5 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.
