Blue Hour palette
Sandy Delta
A quiet five-stop blue hour arc with a confident middle — #004694 carries the weight and #86b9ff carries the air, with #226ecf, #408aee and #5d9bf0 bridging in triadic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
