Mars ditches blue, brown in new dye-free M&M’s for U.S.
Mars will launch M&M’s without certified synthetic colors in August, starting with only red, orange, yellow, and green shells as blue and brown proved harder to reproduce naturally; traditional M&M’s will remain on sale, and the new version will debut online, as Mars faces regulatory pressure and technical challenges in replacing artificial dyes, with broader industry shifts and commercial risks at stake.
