There is a Midrash that relates that the coat of many colors was passed down from Joseph’s forefathers. I imagined that Adam’s coat would both be made of fig leaves as were the coats he and Eve fashioned for themselves, as well as have the qualities of skin and light. Gd fashioned coats of skins עור when Adam and Eve were expelled from the Garden of Eden,"as thin and fine as a second skin, as fingernails”. A Midrash says they were coats of אור , of light. Other commentaries speak of the special glow of light that came from Adam himself.
The fabric chosen for this coat is a transparent metallic organza with a jacquard pattern of leaves. Onto this fabric were superimposed multiple silk screens of fig leaves using metallic pigments.
