The prospect of color changes like butterfly wings

The butterfly-like crystals on the wings of tropical butterflies can provide the needed information to help invent the flow of color-changing clothes on demand.

Hong Kong physicists have discovered the delicate differences between the layers of the butterfly's wings, resulting in countless different colors.

Drawing on this conclusion, the team of the Hong Kong Baptist University has studied three different tropical butterfly species, all of which have distinctive color-changing wings, view.

These include the Ulysses butterfly (also called the blue butterfly when viewed from above), and the butterfly Papilio peranthus from the butterfly phoenix, which is greenish-yellow.

The third butterfly, the Emerald Swallowtail, is dark green, according to the report on the Optical Materials Express website.

However, the colors of the three butterflies are dark blue when viewed from another angle. Since then, experts have discovered that each butterfly has the ability to change color.

When viewed under an electron microscope, they found that the butterfly wings contained layers of fat called snakes called epidermis, alternating with thin layers of air, called laminae . For example, the butterfly Ulysses has seven layers of cuticles, while the P. peranthus butterfly has eight layers.

The laminae layers also contain the epidermis, forming a crystal-like structure for the butterfly wings. This structure is similar to a multi-layer mirror reflecting only a specific wavelength of light.

They claim that the process can be replicated and lead to the creation of corresponding color change materials.
