朱文

noun

raised characters on a seal (appearing red when stamped); yangwen (opposite of baiwen)

Technical term in seal carving (篆刻). Refers to characters carved in relief (raised from the surface), so when stamped with red paste, the characters themselves appear red against the white paper. Contrast with 白文 (baiwen/yinwen), where characters are carved intaglio (recessed), leaving the background raised so the stamped impression shows white characters on a red background.
