Blue Hour palette
Walnut Depot
A quiet five-stop blue hour arc with a confident middle — #004784 carries the weight and #77b8ff carries the air, with #146fc2, #388be0 and #589be4 bridging in tetradic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
