Perennial Gallery
Five stops tuned to sit together without fighting — #006660 ink anchors the set, #7fdad1 opens it up, and #00948b, #39b0a7, #61bdb4 cross the middle in a split-complementary arrangement. Perennial Gallery suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
