Why oranges are orange?

The orange color of oranges is due to the presence of a group of pigments called carotenoids. Carotenoids are natural pigments that are found in many plants, including carrots, tomatoes, and corn. The specific carotenoid that is responsible for the orange color of oranges is called beta-carotene.

Beta-carotene is a precursor to vitamin A, which is an essential nutrient for humans. Vitamin A is necessary for good vision, healthy skin, and a strong immune system. Oranges are a good source of beta-carotene, and eating oranges can help to ensure that you are getting enough of this important nutrient.

In addition to carotenoids, oranges also contain other compounds that contribute to their color. These compounds include flavonoids, anthocyanins, and chlorophylls. Flavonoids are responsible for the yellow color of many fruits and vegetables, while anthocyanins are responsible for the red, purple, and blue colors of many fruits and vegetables. Chlorophylls are green pigments that are found in all plants.

The combination of carotenoids, flavonoids, anthocyanins, and chlorophylls gives oranges their distinctive orange color. The specific color of an orange can vary depending on the variety of orange, as well as the growing conditions.
