chosen: Blueberries get their distinct dark color from the pigment anthocyanin, which is responsible for colors in many fruits and vegetables. This pigment protects the berries from excess ultraviolet light, UVB radiation, infection, and other environmental factors, making it more resilient. In addition, some blueberries contain an antioxidant known as delphinidin, which helps to deepen their intense color. The more antioxidants a blueberry contains, the darker it will be in color.
