Dark anchor, working middle, light release: #00456a, #006ea4, #2f89c1, #5298c8, #6eb4e6 form a split-complementary opera set with somewhere to stand at every lightness. Made for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
