Long before humans figured out how to create colors, nature had already perfected the process -- think stunning, bright butterfly wings of many different hues, for example. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make colored plastics. Their method uses structure -- or the shapes and architectures of materials -- rather than dyes, to produce colors.
