Flavonoids are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans.
Parsley is a source of flavones
Blueberries are a source of dietary anthocyanins
Flavonoids are found in citrus fruits, including red grapefruit
Biological pigments, also known simply as pigments or biochromes, are substances produced by living organisms that have a color resulting from selective color absorption. Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. In some species, pigments accrue over very long periods during an individual's lifespan.
The budgerigar gets its yellow color from a psittacofulvin pigment and its green color from a combination of the same yellow pigment and blue structural color. The blue and white bird in the background lacks the yellow pigment. The dark markings on both birds are due to the black pigment eumelanin.
Anthocyanin gives these pansies their purple pigmentation.
Bougainvillea bracts get their color from betalains
