Structural Colour and the butterfly

Male Morpho Butterflies are bright blue iridescent butterflies, whose colour has been reported to be so intense that they can be seen from low flying aircraft or “up to a quarter of a mile off” in their natural habitat in the rainforests of South America, as states P. Vukusic (1999).

The bright colour is not via pigments. Instead, the butterfly incorporates structural colour via corrugated ridges present on the scales of its wings. This is leading to developments in colour displays and the low-energy thermal imaging cameras

This fascinating video highlights how Lexus is using the scales of the blue morpho butterfly at the nano-level to produce a paint-free colour for the next-generation of luxury cars.
