Colors of Gold

Just as it comes in all shapes and forms, gold equally comes in a variety of colors. The most important thing to know, in relation to this, is that gold is yellow and only yellow. Any other color of gold is actually an alloy, which is a mixture of gold and other metals, even if it’s only one kind of metal. These alloys vary in nature and type to change gold from its original state of bright yellow to the desired color.

Yellow Gold
The original color of gold. In order to add alloys or change the purity of gold without changing its yellow color, silver, zinc and copper are added. The difference, in this case, would be in the tone of the yellow color where pure 24K gold is bright yellow, and less pure types are not as bright.

White Gold
In order to change gold into white, nickel, manganese, palladium or platinum is usually added. To make 18K and 14K white gold, a combination of zinc, copper and nickel is added to the gold. In this case, the less gold, the whiter and the more affordable the jewelry is.

Rose Gold
The mixture of yellow gold with copper and a small percentage of silver is what results in the delicate color of rose. Because copper is cheap, rose gold is usually much more affordable than white and yellow gold.

Pink Gold
The result of using double the amount of silver with the gold and copper combination.

Red Gold
The same components of rose or pink gold minus the silver. Without mixing some silver with the gold and copper to balance the red effect of copper, the result is bright red gold.

Black Gold
Black gold can be made through oxidation using gold and cobalt, electroplating by adding an outer layer to give it a black color, heating enamel on its surface, or simply dying it black.

Green Gold
Green is the color that results from mixing gold with silver. Sometimes green gold, also known as electrum, is also mixed with copper, cadmium or zinc.

Blue Gold
When gold is mixed with iron, gallium or indium, the result is blue gold.

Purple Gold
If aluminum is used as an alloy with gold, it makes purple gold.

Having learned about the colors of gold and how they’re made, this article explains the different types of gold, their uses and, most important, their sturdiness.
