9. Butterfly Wing Nanotechnology — Color Without Pigment

Butterflies like the Morpho butterfly have vibrant blue wings, but the color doesn’t come from pigments. Instead, microscopic structures scatter light in a way that produces brilliant iridescent color.
This phenomenon led to innovations in:
- Anti-counterfeit technology
- Colorfast fabrics that don’t fade
- Energy-efficient displays
- Cosmetic pigments
- Data storage using light refraction
These structural colors are more durable and environmentally friendly than traditional dyes.
