chosen.content: Blueberries aren't bright blue because the pigments in their skin are not intense, so they appear to be lighter in color. Additionally, the blue of the blueberries isn't as pure as artificial colorings, which are responsible for the more vivid colors of many foods. Additionally, the pigments in the skin of blueberries are spread out and less concentrated compared to highly-pigmented fruits like cherries or watermelons. Blueberries also tend to lose their intense hue quickly when exposed to air, sunlight and heat. This explains why deep blue berries often become lighter in color after being picked. Additionally, some hybrids of blueberries contain less pigment than others, further contributing to their dull hue.

rejected.content: Blueberries are not bright blue because their hue is greatly influenced by the presence of chemical compounds known as anthocyanins. These compounds are responsible for the blue, purple and red hues in many fruits, vegetables, and flowers. The concentration and type of anthocyanins found in a particular fruit or vegetable dictate the hue that is visible to the human eye.
