Copper Inn
Five stops tuned to sit together without fighting — #004847 ink anchors the set, #6fb7b6 opens it up, and #007372, #308e8d, #529b9a cross the middle in a tetradic arrangement. Copper Inn suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
