Blue Hour palette
Overcast Manor
A quiet five-stop blue hour arc with a confident middle — #255ea8 carries the weight and #b1d2ff carries the air, with #5289d2, #6da5f0 and #85b5f6 bridging in tetradic formation. Built for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
