Blue Hour palette
Firstlight Fen
Five stops tuned to sit together without fighting — #004f7a ink anchors the set, #73c0f9 opens it up, and #0078b7, #3294d5, #57a3db cross the middle in a complementary arrangement. Firstlight Fen suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
