Sunlit Prairie
Five stops tuned to sit together without fighting — #a32a1f ink anchors the set, #ffb8ac opens it up, and #d05b4c, #ef7767, #f68f7f cross the middle in a complementary arrangement. Sunlit Prairie suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
