Abstract

Colors are seen in nature all around us. When one sees aesthetically pleasing butterfly wings that are blue, gold, or purple it makes nature come alive. Various minerals, such as green jade or blue sapphire also bring color to the forefront of life. But why do these colors exist? Natural selection does have say in the colors in the animal kingdom. However, if one looks to the nanoscale, you can see that the colors of butterfly wings are dictated by the gap between nanostructures inherent to the specific colors of wings observed.

Several butterfly wings and geological minerals of various colors were imaged using a Scanning Electron Microscope (SEM) and the elements of each analyzed using Electron Dispersive Spectroscopy (EDS). Images and data were collected for each and quantum theory principles studied in relating the colors observed due to the nanostructures of butterfly wings and elemental compositions of the mineral species to the electromagnetic spectrum. Planck’s equation was utilized to demonstrate the relationship between energy and wavelength for the different colors of the butterfly wings and elements of the minerals. Similar to using rainbow prisms and visible light calculations of the Balmer series, this brings the interconnection of life and science to students in chemistry classes, by showing the relationship of nature and electron behavior in regards to the world of color.
