Plum Cottage
Five stops tuned to sit together without fighting — #006163 ink anchors the set, #7dd4d6 opens it up, and #008e91, #37aaad, #5fb7b9 cross the middle in a split-complementary arrangement. Plum Cottage suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
