Blue Hour palette
Silvery Bookshop
A quiet five-stop blue hour arc with a confident middle — #004963 carries the weight and #70b9db carries the air, with #007399, #318eb5 and #549cbe bridging in triadic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
