Blue Hour palette
Crackling Harbor
A quiet five-stop blue hour arc with a confident middle — #00417f carries the weight and #6fb1ff carries the air, with #0668c1, #3084df and #5194e3 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.
