I don't understand what the differences are red, yellow, blue etc are, and why only red coloring is unsafe. I normally shop at Costco, Sam club, Safeway, giant, trader Joe and Asian supermarket.
Start reading ingredients. You should understand what each word says. Red yellow and blue are literally colors used to dye foods certain colors - the dyes are ALL bad. They are banned in the EU, I believe. The US has very lax standards for food safety.
