Anthocyanin pigments / colors

There are hundreds of different anthocyanins, with over 600 to 700 identified, varying by sugar attachments and modifications, but they are all derived from about 17 core anthocyanidin structures, with just six (cyanidin, delphinidin, pelargonidin, peonidin, petunidin, malvidin) making up most of the common pigments. Pelargonidin Orange-red or brick red Cyanidin Magenta, crimson, or reddish-purple Peonidin Magenta or purplish-red Delphinidin Blue-reddish, purple, or blue-violet Petunidin Dark-red or purple Malvidin Bluish-purple or blue-red The type of anthocyanin produced by a plant is fundamentally determined by its genetics. However, the environment can significantly influence the amount of anthocyanin produced and can affect factors like pH that subtly change the resulting color (hue). Combined with senescence, you can get some sensational rainbow colours.
