Reason why there are gold other than yellow gold.
Gold also has colors other than gold. This is because products are often made in the form of alloy that are resistant to scratches. For example, for 18K gold, the percentage of gold is 75%, and the remaining 25% will be other metals. Depending on what and how much metals you used on this product, the color changes slightly and is said to use to match the design of jewelry or other products.
Colors beside yellow gold
Here is a list of well-known gold aside from yellow gold, green gold, yellow gold, pink gold, red gold and white gold. If the purity of gold is 75%, green gold is used with silver for all of the remaining 25%. On the other hand, yellow gold is used about the same amount of silver and copper, and red gold is the one with a high percentage of copper. Pink gold slightly more whitish than red gold, about 80% of 25% of which is copper. White gold contains about 5% of 25% palladium or nickel.
