There are also different gold colors, depending on how it’s alloyed with other metals. Silver, copper, and zinc are the most common metals to be alloyed with gold for jewelry production. The final color and shade also vary depending on the percentage and type of metal used. Some popular gold colors include:

Yellow gold is the purest color available and the most common one used for engagement and wedding rings. It achieves its color through the combination of copper, silver, and pure gold.
White gold is a popular color for jewelry with the advantage of being more durable and affordable than yellow gold. It’s made by mixing gold with alloys like zinc, copper, and palladium (platinum).
Rose gold achieves its unique color by incorporating about 25% copper and less silver. This color is also known as pink gold or red gold, and the difference between them is the copper content. The more copper used, the stronger the red coloring.
Green gold, also known as electrum, is an alloy of gold, silver, and occasionally copper. Cadmium can provide more green coloring but it’s not often used due to toxicity concerns.
Gray gold is a mix of gold and palladium. However, a less expensive alternative to produce this gold color is by replacing palladium with silver, copper, and manganese.
