Many insects have wings that can change color.
Their wings are covered with multiple layers of fine hair. Each layer reflects light at a slightly different angle from the other. The interference among the reflected wavelengths result in shimmering colors which look slightly different from different angles. Mercedes-Benz, and Ford are now offering cars that change colors. Their special paints consist of fine strands of polyester that can give rise to interference patterns of light like an insect's wings.
