The color of the flowers is generally caused by anthocyanin pigments
Explanation:
Anthocyanins are hydrosoluble vacuole pigments from the family of flavonoids. Anthocyanins are characteristics of flowers that have distinct colors depending on the pH (i.e., red, blue, purple, etc). These phytochemicals are commonly present in different parts of the plant including stems, roots, leaves, flowers and fruits.
