There are 3 groups, or 6 types, of red anthocyanin compounds:

1. pelargonidin [orange, salmon] & [orange, red] e.g. strawberries

2. cyanidin [red] & [magenta] e.g. red-skin fruits & vegi
   > peonidin [purplish red] & [red-brown] e.g. rose flower

3. delphinidin [blue, purple] & [blue] e.g. grapes
   > malvidin [purple] & [purple]
   > petunidin [purple] & [dark red]

A typical anthocyanin pigment appears red in acid, violet in neutral, and blue in alkaline solution.
Intense light and low temperatures favour the development of anthocyanin pigments.

3-Deoxyanthocyanidins are yellow anthocyanidins. 3-Deoxyanthocyanidins are reported to be stable to color loss due to change in pH.
