Mustard Hollow
Five stops tuned to sit together without fighting — #7c002b ink anchors the set, #fb8093 opens it up, and #b5274c, #d54765, #db6478 cross the middle in a analogous arrangement. Mustard Hollow suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
