Mercurial Harbor
Five stops tuned to sit together without fighting — #006467 ink anchors the set, #7ed8db opens it up, and #009196, #38adb2, #61babe cross the middle in a analogous arrangement. Mercurial Harbor suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
