Blue Hour palette
Amber Bluff
A quiet five-stop blue hour arc with a confident middle — #004165 carries the weight and #6bafe1 carries the air, with #0069a0, #2e84bd and #4f93c4 bridging in tetradic formation. Built for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
