Changing the color of gold

A University of Southampton, UK, team discovered that by embossing tiny raised or indented patterns onto the metal’s surface they can change the way it absorbs and reflects light – ensuring our eyes don’t see it as ‘golden’ in color at all. The finding results from a major initiative funded by the Engineering and Physical Sciences Research Council (EPSRC) targeting the development of a new generation of nanotechnology-enabled materials.
Equally applicable to other metals such as silver and aluminum, this breakthrough opens up the prospect of coloring metals without having to coat or chemically treat them..."
