Trick or Treat!
Both types of M&Ms in this picture are dyed with natural colors!
The candy on the left is sold in Europe, where Mars and other candy companies have reformulated their products with mostly natural dyes to look almost like the synthetically-dyed originals. Europe requires health warnings on most candy with synthetic dyes. (Blue 1 is not included in the warning, so the blue candies on the left are the only ones in the picture that are not naturally dyed.)
The candy on the right is a M&M’s peanut candy with colors from all-natural sources, a new product being made available in the United States.
