Granite Mesa
Five stops tuned to sit together without fighting — #a40000 ink anchors the set, #ffac9f opens it up, and #d34739, #f36554, #f97f6f cross the middle in a triadic arrangement. Granite Mesa suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
