Some of the colors of autumn leaves are derived from anthocyanins. [1] [2] Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway.
This can happen when an air layer is located just under the epidermis resulting in a white or silvery reflection. [8] It is sometimes called blister variegation.

The range of colours of natural iridescent objects can be narrow, for example shifting between two or three colours as the viewing angle changes, [5] [6] An iridescent biofilm on the surface of a fish tank diffracts the reflected light, displaying the entire spectrum of colours ...
