Colours gold and sliver

Hi is their any possible way that you could get the colours gold and sliver ?

ive just been picking a light grey for silver
and in the yellow orange range click on bronze colour for gold

Yeah same was just wondering if their was any codes or something to make the colours

You don't need codes. You can just type in 'silver' or 'gold' in color picker input field and it will select the color automatically.
