So, when the amount of gold is kept constant, the more the percentage of white metal, the paler the yellow color. Similarly, the presence of copper increases the red hue of gold making it more rosy than yellow. The less the percentages of these metals the yellower the resulting gold will be.

Some look bright yellow, others look more orange, some even look green. Why is this? It’s because of heat, alloys and manufacturing. Manufacturers use slightly different alloys in their gold mix that can change how gold looks. Some companies use a little bit more copper, which gives it more of a orange or reddish color. Other companies use more nickel.

Yellow gold. Yellow gold is described as such because of its yellow colour which is a result of it being alloyed with silver and copper. 9 carat yellow gold is often a lighter yellow colour than 18 carat yellow gold, which is more of a rich and intense yellow due to its higher gold content. 9 carat yellow gold. 38% Gold. 10% Silver. 52% Copper ...

While 24K gold is very rare in rings, it can be encountered more often in earrings as they get subjected to a smaller amount of wear and tear. 24K gold has the advantage of an intense yellow color tone, whereas it is tough to distinguish between 10K, 14K, and 18K gold with your bare eyes.

Those 'other' gold colors are made of up alloys. Alloys are new metals that are created by combining two or more different metals. Even standard yellow gold (the true gold color) is made up of alloys unless it is 24k pure gold. Here are 8 things you should know about gold colors:

A. Yellow karat golds are alloys of gold, copper, and silver. In most, there is also a little zinc added, which I believe is to improve the melting characteristics. 18K gold is 18/24, or, 75% gold. The copper in the 18K alloy usually varies between 5 to 15% and the silver between 10-20%.

Some of the additional white metals used are palladium, manganese and zinc. The resulting white gold can have a yellowish hue, whose intensity will depend on how much white metal is mixed in – after all, a significant part of the material still consists of yellow gold. To remove this yellow tinge, many jewelers plate white gold with rhodium.

So why does white gold turn yellow? As the plating is only a very thin top layer, the rhodium tends to fade over time. This is especially true around prongs and corners, which gets the most wear and tear.

Einstein’s theory tells us that at these speeds the mass of the electrons increases, which in turn means the energy needed to kick them up to another orbital is reduced. So lower-energy blue photons are absorbed, and don’t get reflected by the gold. And if blue is removed, we see yellow.

You’ve probably not given it much thought, but the reason why gold is yellow (or rather, golden) is deeply ingrained in its atomic structure — and it’s because of something called ...
