Walnut Manor
Five stops tuned to sit together without fighting — #8e1c13 ink anchors the set, #ff9e8e opens it up, and #bb4e40, #da6a5a, #e18172 cross the middle in a analogous arrangement. Walnut Manor suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
