During ripening, which pigment accumulates in red grape skins?

Explanation:
Anthocyanins accumulate in red grape skins as the fruit ripens, giving the characteristic red color. These pigments are produced and deposited in the skin’s vacuoles starting at veraison and continue increasing during ripening. Chlorophyll, the green pigment, breaks down during this process, so green fades away. Carotenoids, including xanthophylls, contribute yellow to orange hues but do not create the red coloration. So the pigment responsible for the red skins is anthocyanins.
