Blue Hour palette
Umber Patio
A quiet five-stop blue hour arc with a confident middle — #004382 carries the weight and #73b3ff carries the air, with #0069c6, #2e85e4 and #5096e7 bridging in analogous formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
