Butterfly broch collection
The structural color of butterflies stems from the specific structure of the butterflies' wings which explains why it shifts and appears so intense. This is known as IRIDESCENCE and it occours more in nature than you think. Mother of pearl seashells, fish and peacocks are just few examples of animals with this quality, but it is most pronounced in the butterly family. It happens when light passes through a transparent, multilayered surface and is reflected more than one. The multiple reflections compound one another and intensify colours.
