Nowhere in nature is there so much beautiful color as on the wings of butterflies. Scientists, however, are still baffled about exactly how these colors are created. One young scientist has been examining the structure of the surface of the wings of the cabbage white and other butterflies in great detail. He notes that the colors on butterfly wings are created in two different ways: via pigments and via nanostructures on the scales, which ensure that light is distributed in ways that are sometimes spectacular.
