In 2012, French beekeepers encountered an unusual phenomenon when they discovered blue and green #honey in their hives. This strange coloration immediately aroused the interest and curiosity of beekeepers, and they went in search of the cause. In their investigations, they found that the bees were collecting colored sugar from a nearby M&M factory.

The factory had left remnants of colored sugar in the candy manufacturing process, and the bees had used this sugar as a food source.
