Glassy Crater
Five stops tuned to sit together without fighting — #005280 ink anchors the set, #75c3ff opens it up, and #007bbd, #3397db, #58a6e0 cross the middle in a split-complementary arrangement. Glassy Crater suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
