Blue Hour palette
Herbal Marsh
Five stops tuned to sit together without fighting — #00466d ink anchors the set, #6eb5eb opens it up, and #006ea9, #2f89c6, #5298cd cross the middle in a tetradic arrangement. Herbal Marsh suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
