Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold.
Sometimes it depends on how the light interacts not just with one molecule, but with a whole bunch of molecules. The colour of gold metal is only yellow when we have a large lot of gold atoms. Small particles of gold may be coloured purple or red. And we cannot really say what colour a single gold atom is.Sometimes the colour of an object does not depend on its molecules at all, but is a funny effect of its shape. It is possible for a regular shape pattern to make some wavelengths of light cancel themselves out.he colour of gold metal is only yellow when we have a large lot of gold atoms.
