FD&C Red 3 is associated with which colorant?

Explanation:
FD&C color numbers point to a specific dye, and Red 3 is the dye called erythrosine. This iodine-containing xanthene dye is the colorant designated as FD&C Red No. 3, giving a pinkish-red shade used in various foods and products. The other colorants map to different color numbers—Allura Red is Red 40, Quinoline Yellow is a yellow dye, and Phloxine B is a different red dye—so erythrosine is the one specifically associated with Red 3.
