Is gold pure gold?

24K gold is definitely yellow, and 18K gold and 14K gold can be yellow or rose. It should be said that pure gold (24K gold) is yellow, while impure 18K gold and 14K gold were yellow before, and now they are rose.

Platinum is actually not gold (gold element) but platinum (platinum element). Platinum is also a precious metal, and its price is similar to that of gold. Pure white gold is silvery white.
