1622, "of a bluish-leaden color," from M.Fr. livide, from L. lividus, from livere "be bluish," from PIE *(s)liwos-, from base *(s)li- "bluish" (cf. O.C.S., Rus. sliva "plum;" Lith. slywas "plum;" O.Ir. li, Welsh lliw "color, splendor," O.E. sla "sloe"). The sense of "furiously angry" (1912) is from the notion of being livid with rage.
