Blue Hour palette
Sienna Mill
A quiet five-stop blue hour arc with a confident middle — #00578a carries the weight and #86c9ff carries the air, with #0081c8, #349de6 and #5badeb bridging in tetradic formation. Built for bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
