Mustard Crossing
Five monochrome stops with room to breathe — #00456d grounds, #006da9 and #2f88c6 do the talking, #5197cd softens, #6eb4ea lifts. The complementary bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
