General Mills, the U.S.-based maker of multi-colored kids' cereal Trix, said it will bring back the original, artificially-colored version after customers complained.
"Classic Trix," which is colored artificially, will sit on store shelves alongside the new, natural-flavor version, the company said.
General Mills introduced the natural-flavor version last year, replacing artificial colors and flavors with coloring made from radishes, purple carrots and turmeric.
But customers have complained, with one reportedly calling the new product "basically a salad," the Wall Street Journal reported on Thursday. Another said she liked the way the artificial colors and high-fructose corn syrup look and taste, the report said.
A General Mills spokesperson told CNBC that the new product will remain on the shelves as it "has its own fan base."
