Blue Hour palette
Autumn Brook
A quiet five-stop blue hour arc with a confident middle — #11447a carries the weight and #89b2e5 carries the air, with #3e6ca3, #5887c0 and #6e96c7 bridging in analogous formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
