M&M’s Is Quietly Losing Two Classic Colors

M&M’s is turning 85 this August and the birthday gift is… a slightly less colorful bag of candy.

As Mars moves toward replacing artificial food dyes with natural alternatives, two of M&M’s most recognizable colors―blue and brown―are temporarily disappearing from a new version of the classic candy. And the reason is surprisingly complicated.

The naturally colored M&M’s are set to launch in August. But before anyone starts mourning the loss of blue candies forever: the original artificially colored version isn’t going anywhere. The change only applies to the new dye-free version, which will initially be sold through Amazon. Still, it raises a very important question.

Why are two tiny candy colors causing such a big problem?

Blue Was Apparently The Hardest Color To Make

Mars has already figured out how to recreate red, orange, yellow, and green using natural colors. Blue, however, is proving to be the problem child. The issue is that M&M’s iconic blue color isn’t just any blue. The shade was introduced in 1995 after a nationwide fan vote, meaning it has been part of the candy’s identity for more than 30 years. Replacing it isn’t as simple as finding a slightly different shade and moving on.

Mars has been experimenting with spirulina, a blue-green algae extract, as a natural alternative. The problem? It’s expensive, difficult to work with, and apparently much harder to use consistently at the scale required for one of the world’s biggest candy brands. And somehow, brown got caught up in the problem too. Because even though brown seems like the easiest color to recreate, the dye process relies on blue as part of the formula. No blue dye means no brown M&M’s either.

Which means two of the favorite colors in the bag are suddenly the ones causing the biggest headache.

The Weird Thing About M&M’s Is That The Colors Matter

Nobody is eating an M&M and thinking: “Wow, this shade of blue tastes incredible.” The flavor is the same. The chocolate is the same. But M&M’s has spent decades proving that the colors are part of the experience. Blue wasn’t randomly added. It was voted in by millions of people. Brown became a character in the brand’s advertising. The colors are basically part of the personality of the candy.

Which is why changing them feels bigger than changing the packaging on a cereal box. The product is still the same. It just looks slightly less like the version people remember.

A Preview Of The Future Snack Aisle?

The M&M’s change is part of a much bigger shift happening across packaged food. Brands are under increasing pressure to remove artificial colors and replace them with natural alternatives. But M&M’s shows that making those swaps isn’t always as easy as removing one ingredient and adding another. Sometimes the hardest part isn’t changing how food tastes. It’s changing something people recognize instantly.

For now, blue and brown M&M’s aren’t disappearing completely. They’re just taking a temporary break while Mars figures out how to recreate a tiny piece of candy history without artificial dyes. Which seems like a very 2026 problem to have. A billion-dollar company trying to recreate a blue chocolate button.
