You may think you know your color wheel, but the stories behind these rare colors around the world just might blow your mind.

Abstract Pigments produced by submerged fermentation of three filamentous fungi isolated from Brazilian caves, namely Aspergillus keveii, Penicillium flavigenum, and Epicoccum nigrum, were submitted ...

A conspicuous yellow pigment produced by the bacterium (YAS – Yellow Affinity Substance) plays a key role in this process. YAS preferentially attaches itself to cellulose fibers.

A conspicuous yellow pigment produced by the bacterium (YAS—Yellow Affinity Substance) plays a key role in this process. YAS preferentially attaches itself to cellulose fibers.

Our previous studies have also demonstrated that the pigments responsible for the formation of yellow flowers are flavonoids in ‘High Noon’ (P. suffruticosa × P. lutea), with tetrahydroxychalcone, ...

These health issues could also lead to changes in how carotenoids—plant-based pigments that turn feathers red, orange, and yellow—are expressed. Although this alternative theory is plausible, ...
