Researchers at Nagoya University created a material containing photochromic dyes, crystals providing structural coloration, and a colored background that mimics the color changes that animals such as frogs, chameleons, and octopuses can display. This material could display different patterns and images depending on whether it was exposed to visible or ultraviolet light, or had a white or black background, which suggests its potential application in a range of next-generation display technologies.

A range of creatures, including chameleons, octopuses and frogs, can change color in response to changes in the environment. Some insights into the mechanisms behind this at the anatomical, cellular and molecular levels have been obtained. However, much work is still required to obtain sufficient understanding of this phenomenon and to translate it into useful artificial applications.
