so thin as to transmit light; "a hat with a diaphanous veil"; "filmy wings of a moth"; "gauzy clouds of dandelion down"; "gossamer cobwebs"; "sheer silk stockings"; "transparent chiffon"; "vaporous silks"
furiously angry; "willful stupidity makes him absolutely livid"
(of a light) imparting a deathlike luminosity; "livid lightning streaked the sky"; "a thousand flambeaux...turned all at once that deep gloom into a livid and preternatural day"- E.A.Poe
