Brazen Estuary
Five stops tuned to sit together without fighting — #00407d ink anchors the set, #76b0f5 opens it up, and #2168b4, #3f83d2, #5a93d7 cross the middle in a triadic arrangement. Brazen Estuary suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
