Plant Pigments - an overview | ScienceDirect Topics Plant pigments, a generic term used to designate a large number of colored molecules, can be classified into tetrapyrroles (e.g., chlorophyll) and carotenoids (e.g., β-carotene and xanthophyll). Of the pigments, carotenoids are fat-soluble (lipophilic) natural pigments which are synthesized by plants and some microbes. Leaf Pigments | Harvard Forest These are responsible for the pink-red colors of most flower petals, of most red fruits (like apples) and almost all red leaves during the autumn. Anthocyanins absorb light in the blue-green wavelengths, allowing the red wavelengths to be scattered by the plant tissues to make these organs visible to us as red.
