Monochrome palette
Leaden Cellar
A quiet five-stop monochrome arc with a confident middle — #004755 carries the weight and #6eb6c9 carries the air, with #007186, #308ca2 and #529aac bridging in analogous formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
