Real gold can indeed be different colors, and this phenomenon is due to the presence of other metals alloyed with gold. These alloys change the color, hardness, and other properties of the gold, allowing for a variety of hues beyond the traditional yellow.
What Colors Can Gold Be?
Gold can appear in several colors, depending on the metals it is alloyed with. Here are some common variations:
- Yellow Gold: The classic gold color, achieved by mixing pure gold with metals like silver and copper.
- White Gold: Created by alloying gold with metals such as palladium, silver, or nickel. It often has a rhodium plating for a brighter finish.
- Rose Gold: Known for its pinkish hue, rose gold is a blend of gold, copper, and sometimes a bit of silver.
- Green Gold: This rare color is achieved by mixing gold with silver, sometimes with a hint of copper.
- Blue Gold: Formed by alloying gold with indium or gallium, resulting in a unique blue tint.
- Purple Gold: A brittle alloy created by mixing gold with aluminum, giving it a striking purple color.

The color variations in gold are due to the different metals mixed with it. Each metal brings its own properties:
- Copper: Adds a reddish tint, resulting in rose gold.
- Silver: Lightens gold, producing green or white gold.
