Gold is a colour in itself. It's a sort of shiny yellow colour. You can also buy rose gold, white gold, green gold, pale yellow gold, and red gold.

Today gold in its pure "shiny yellow" form is rarely used to produce jewelry. Twenty-four-karat gold is too soft and not durable enough to use for jewelry. Jewelers use different alloys, combining gold with other metals to give it more hardness. For example, the most popular grade of gold purity in the United States is 18-karat, meaning three-quarters of the alloy is gold and one-quarter is a mixture of copper and silver. Mixing in silver and copper is a bit of science-if too much silver is added, the gold will show a green tinge. On the other hand, mixing in too much copper will give gold a red tinge (so-called "rose gold"). Addition of nickel or palladium overpowers the distinctly bright yellow color of gold, producing what is known as "white gold." Mixing other metals with gold produces a variety of colored golds, such as green gold , pale yellow gold , yellow gold, red gold, and white gold.
