Most of the colors on today's paper and fabric are made using dyes or pigments. But colors can also be produced by modifying a material's surface at the nanoscale, causing the surface to reflect or scatter different frequencies of light and giving these materials "structural color." Butterfly wings and bird feathers are examples of materials that naturally exhibit structural color.
