Peacock feather

Peacock feather. Peacocks are known for their bright colors. However, when their feathers are wet they appear brown which indicates that the bright colors aren’t a result of pigmentation. Something else is going on! Peacocks achieve its stunning plumage display through structural coloration, more commonly known as iridescence. Structural coloration results from a lightwave interaction with the surface. The light can be reflected, refracted, or sometimes both, and the effect is angle dependent. Depending on the angle and the wavelength, lightwaves may constructively or destructively interfere with each other resulting in different colors and brightness.
