Emerald Heath
Five stops tuned to sit together without fighting — #871c2c ink anchors the set, #f89a9c opens it up, and #b34c53, #d2676d, #da7e80 cross the middle in a triadic arrangement. Emerald Heath suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
