Blue Hour palette
Perennial Deck
A quiet five-stop blue hour arc with a confident middle — #004173 carries the weight and #6bb0f4 carries the air, with #0068b3, #2d84d1 and #4f93d6 bridging in analogous formation. Built for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
