Emerald Reef
Five stops tuned to sit together without fighting — #005e89 ink anchors the set, #90d0f9 opens it up, and #3b88b5, #58a4d2, #74b3db cross the middle in a triadic arrangement. Emerald Reef suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
