Blue Hour palette
Harbor Lighthouse
Five stops tuned to sit together without fighting — #005497 ink anchors the set, #92c6ff opens it up, and #367ec6, #529ae4, #6eaae9 cross the middle in a split-complementary arrangement. Harbor Lighthouse suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
