Blue Hour palette
Tranquil Library
A quiet five-stop blue hour arc with a confident middle — #004a5b carries the weight and #70b9d1 carries the air, with #00748e, #318faa and #549db4 bridging in tetradic formation. Built for podcast cover art at sixty pixels square. The darkest and lightest stops clear AA for large text.
