Lichen Bluff
Five stops tuned to sit together without fighting — #004967 ink anchors the set, #70b8e1 opens it up, and #00729f, #308dbc, #539cc4 cross the middle in a complementary arrangement. Lichen Bluff suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
