Bees can see colors that are invisible to humans, such as ultraviolet light. Many flowers have distinctive ultraviolet color patterns that are invisible to the human eye but are incredibly eye-catching to bees. These patterns help target the areas of nectar and act as beacons directing bees towards a flowers center. According to research, bees favorite colors are purple, violet, and blue. Bees cannot see the color red, but they can easily distinguish between dark and light, making them very good at seeing edges.
