Origin: 1585–95; < Middle French, feminine of incarnadin flesh-colored < Italian incarnatino, equivalent to incarnat(o) made flesh (see incarnate) + -ino-ine1; see carnation
1591 (adj.) "flesh-colored," from Fr. incarnadine, from It. incarnadino "flesh-color," from L.L. incarnatio (see incarnation). The verb properly would mean "to make flesh colored," but the modern meaning "make red," and the entire survival of the verb, is traceable to "Macbeth" II ii. (1605).
