Etymonline
Word Origin & History

lac
"red resinous substance," 1553, from Pers. lak, from Hindi lakh (Prakrit lakkha), from Skt. laksha, which according to Klein is lit. "one hundred thousand," in ref. to the insects that gather in great numbers on the trees and make the resin run out. But others say lakh is an alteration of Skt. rakh,
from an IE root word for "color" [Webster]. Still another guess is that Skt. laksha is related to Eng. lax, lox "salmon," and the substance was perhaps originally so called from being somewhat the color of salmon.

lac

sticky, resinous secretion of the tiny lac insect, Laccifer lacca, which is a species of scale insect. This insect deposits lac on the twigs and young branches of several varieties of soapberry and acacia trees and particularly on the sacred fig, Ficus religiosa, in India, Thailand, Myanmar (Burma), and elsewhere in Southeast Asia. The lac is harvested predominantly for the production of shellac (q.v.) and lac dye, a red dye widely used in India and other Asian countries. Forms of lac, including shellac, are the only commercial resins of animal origin
