Aurora palette
Birch Library
A quiet five-stop aurora arc with a confident middle — #253a7c carries the weight and #91aae7 carries the air, with #4a63a5, #637ec2 and #768ec9 bridging in triadic formation. Built for packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA as a text pair.
