Pavonine refers to a vibrant, iridescent coloration resembling that of a peacock's feathers. The term is derived from the Latin word "pavoninus," which means "of a peacock." This striking quality is often seen in various species of birds, insects, and even some minerals, where light interacts with microscopic structures to create a shimmering effect. In nature, pavonine colors serve various purposes, such as attracting mates or camouflaging against predators. The phenomenon is not limited to living organisms; it can also be observed in materials like opals and certain types of glass, where the surface structure produces similar iridescent effects.
