Thanks to a few genetic tweaks, your margarita could someday come in a lovely lavender shade—and be better for your health, too. Researchers at the University of Florida Citrus Research and Education Center have modified the genetic code of limes, making the popular fruit more resilient and healthier for you, and giving it a colorful new tinge. The researchers will publish their work in the January issue of the Journal of the American Society for Horticultural Science, according to a press release.

The limes get their new purple hues from molecules called anthocyanins, which also give blueberries and red wine their distinctive shades. By adding genes from purple grapes and blood oranges to Mexican limes, the researchers created a lime that could synthesize its own anthocyanins. The researchers found that the new genes also changed the color of the lime's roots and leaves.
