Blue Hour palette
Rocky Library
A quiet five-stop blue hour arc with a confident middle — #005da5 carries the weight and #a4d0ff carries the air, with #0086e9, #45a3ff and #6bb4ff bridging in analogous formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
