Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content – the higher the copper content, the stronger the red coloration. A common alloy for rose gold is 75% gold and 25% copper by mass (18 karat). Since rose gold is an alloy, there is no such thing as "pure rose gold".

A common formulation for red gold is 50% gold and 50% copper.

Up to 15% zinc can be added to copper-rich alloys to change their color to reddish yellow or dark yellow.
