Gold is available in several different colors. The most popular is yellow gold, followed by white gold and rose gold, though other gold colors are sometimes also available such as bronze, red and lime gold.

Jewelry can also be made using a combination of different gold colors. These jewelry items are sometimes called two-tone, three-tone or multi-colored gold. The gold content of yellow gold is measured in the same way it is measured in for example white gold. So an 18kt white gold ring contains 75% pure gold, just as 18kt yellow gold contains 75% pure gold.
