The Greek word origin of anthocyanin is "flower" ἀνθός (anthos) and "blue" κυανός (kyanos). Water-soluble pigments from flowers and fruits in red, blue, and purple are originally called anthocyan. The flavonoid backbone without sugar (shown below) is called anthocyanidin (it is called aglycon because it is devoid of glyco moiety), and structure with sugars is called anthocyanin. Except for carotenoid (yellow) or indigo (deep blue), most pigments of plant origin are anthocyanins.
Target of fruit and flower color engineering
Anthocyanin contains 3 aromatic rings, and glycosylation at the 3-OH position is necessary for stabilizing the aromatic ring. The general color of anchocyanin is red in acidic environment and purple/blue in alkali. The colors are, however, dependent on many other factors such as additional modifications and metal ions as is suggested by multi-color flowers such as pansy (yellow, orange, purple, violet, deep blue).
