There might actually be a useful purpose for having a favorite color — at least if you're a bee.

The favorite color of the buff-tailed bumblebee (Bombus terrestris), violet in its case, could help it find more sweet nectar, scientists now find.

Researchers took bees that had never seen real flowers from nine southern Germany bumblebee colonies and exposed them to violet or blue artificial flowers in the lab. The investigators found these bees — one of the most numerous bumblebee species in Europe — often prefer violet to blue, seemingly innately.
