Blue Hour palette
Woolen Gazebo
A quiet five-stop blue hour arc with a confident middle — #004f60 carries the weight and #73c0d6 carries the air, with #007a93, #3395af and #57a3b9 bridging in tetradic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
