Flesh-colored, especially flushed with deep red; blood-tinged as if life itself had risen close to the surface (literary). The word carries bodily implication, redness with skin beneath it.

Turn red, especially as if stained with blood (literary).

From Italian incarnadino “flesh-colored,” from incarnare “to make flesh,” from Latin incarnare (in- “in” + caro/carn- “flesh”). The word’s color is inseparable from its metaphor: redness as embodiment.
