Anthocyanin

Anthocyanins (also anthocyans; from Greek: ἄνθος (anthos) and κυάνεος/κυανοῦς kyaneos/kyanous ) are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart gave the name Anthokyan to a chemical compound that gives flowers a blue color for the first time in his treatise “Die Farben der Blüthen”.
