Biomimicry with Artificial Structural Colors | Communication design | Scoop.it

"Bright colors in the natural world often result from tiny structures in feathers or wings that change the way light behaves when it’s reflected. This structural color is respon­sible for the vivid hues of birds and butter­flies. Arti­ficially harnessing this effect could allow us to engineer new materials for appli­cations such as solar cells and chame­leon-like adap­tive camou­flage. Inspired by the deep blue colora­tion of a native North American bird, Stellar’s jay, a team at Nagoya Uni­versity reproduced the color in their lab, giving rise to a new type of arti­ficial pigment. “The Stellar’s jay’s feathers provide an excellent example of angle-inde­pendent structural color,” says Yukikazu Takeoka, “This color is enhanced by dark materials, which in this case can be attri­buted to black melanin particles in the feathers.”
