Birch Fen
Five stops tuned to sit together without fighting — #3660a6 ink anchors the set, #b9d3ff opens it up, and #608ad0, #7ba6ee, #91b6f4 cross the middle in a split-complementary arrangement. Birch Fen suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
