We always want to see things in a different way, like what if the colour of GOLD is no more golden? What if we could change the colour of GOLD?
Scientists have for the first time found a way to change the colour of GOLD, the world's most iconic precious metal. Researchers from the University of Southampton, USA, have discovered that by embossing tiny raised or indented patterns onto the meta's surface, they can change the way it absorbs and reflects light. The result is that the human eye does not see it as "GOLDEN" in colour at all.
The breakthrough finding is equally applicable to other metals such as aluminium and silver. It opens up the prospect of colouring metals without having to coat or chemically treat them, delivering valuable economic, environmental and other benefits.
The technique could be harnessed in a wide range of industries which includes manufacturing jewellery. It can also be used to make banknotes and documents that are harder to forge. It can be used to produce a wide range of colours on a given metal.
