Blue Hour palette
Flint Manor
A quiet five-stop blue hour arc with a confident middle — #00466f carries the weight and #6fb6ed carries the air, with #006fab, #308ac8 and #5299cf bridging in triadic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
