                                The question, "Is amaranth Red 40?" arises from widespread confusion about artificial food colorings, but they are not the same substance. Amaranth, known as FD&C Red No. 2, is a distinct dye that was replaced by Red 40, or Allura Red AC, in the United States after safety concerns led to its ban.
