Blue Hour palette
Indigo Grove
A quiet five-stop blue hour arc with a confident middle — #004370 carries the weight and #6db2ee carries the air, with #006bad, #2e86ca and #5196d0 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.
