Oaken Mill
Five stops tuned to sit together without fighting — #8c3a00 ink anchors the set, #ffb089 opens it up, and #c65a14, #e57639, #ec8d5c cross the middle in a triadic arrangement. Oaken Mill suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
