Weevil not be ignored!

"The ultimate aim of research in this field is to figure out how the weevil self-assembles these structures, because with our current technology we are unable to do so," Dr. Saranathan said. "The ability to produce these structures, which are able to provide a high colour fidelity regardless of the angle you view it from, will have applications in any industry which deals with colour production. We can use these structures in cosmetics and other pigmentations to ensure high-fidelity hues, or in digital displays in your phone or tablet which will allow you to view it from any angle and see the same true image without any colour distortion. We can even use them to make reflective cladding for optical fibres to minimise signal loss during transmission."

Here's a true color geek Halloween costume: the Philippine Snout Weevil.
 
Scientists from Singapore and Switzerland are studying the colors on the Philippine Snout Weevil.  This colorful little guy reproduces all the colors of the rainbow in concentric circles on its body, and does so by varying the size and volume of the scales on its exoskeleton.  No pigments involved!  It is said that human technology has no current means of reproducing this phenomena.  Of particular interest is the way these colors do not change hue when viewed at different angles.
