Blue Hour palette
Zephyr Alley
A quiet five-stop blue hour arc with a confident middle — #004166 carries the weight and #6bafe2 carries the air, with #0069a1, #2e84be and #4f93c5 bridging in analogous formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
