I’m positive that color is found in nature so that has to make it healthy and/or safe to ingest, right?
I don’t know if the dye in the Slurpee/Icee/Squishee is the same one or not, but that color can be found in nature. The dye called Carmine is a deep red like that and is made from Cochineal insects, so…yeah, definitely found in nature.
But you probably didn’t want to know all that.
