Some of your favorite candy is about to undergo a big change.

Mars Inc. announced plans to get rid of all artificial colors from all of its human food products. According to a press release by the company, some of its products are already made without the use of artificial colors, but now it’s expanding those standards to all chocolate, gum, confection, food, and drink. The change will affect over 50 Mars-owned brands including M&M’s, Skittles, Wrigley’s gum, Snickers, and Twix.

It plans to implement the change over the next five years.

“We’re in the business of satisfying and delighting the people who love our products,” Mars Inc. president and CEO Grant F. Reid said in the release. “Eliminating all artificial colors from our human food portfolio is a massive undertaking and one that will take time and hard work to accomplish.”

The company will work with suppliers to identify natural alternatives while maintaining the “vibrant, fun colors” that customers expect.
