While pure gold is yellow in color, colored gold can be developed into various colors. These colors are generally obtained by alloying gold with other elements in various proportions.
For example, alloys which are mixed 14 parts gold to 10 parts alloy create 14-karat gold, 18 parts gold to 6 parts alloy creates 18 karat, and so on. This is often expressed as the result of the ratio, i.e.: 14/24 equals 0.585 and 18/24 is 0.750. There are hundreds of possible alloys and mixtures, but in general the addition of silver will color gold white, and the addition of copper will color it red. A mix of around 50/50 copper and silver gives the range of yellow gold alloys the public is accustomed to seeing in the marketplace. A small amount (0.2%) of zinc can be added to harden the alloy.
The most common grades of gold, in addition to pure 24K, are 22K (92%), 18K (75%), 14K (58%) and 9K (38%).
Colored golds can be classified to three groups:
White gold is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats.
Back from the window
Everything's subtle
Temporary sanctuary
Look through the window
Everything's subtle
Tailored to fit, but nothing's that simple
Gold, you will always come to me
With the power of deception
Gold won't ever comfort me
The color of deception
The color of deception
Move closer
Subterfuge
Illusion's there for all to see
There's no one left to rescue me
Glass and stone, it cuts like a knife
And gold won't ever comfort me
Gold, you will always come to me
With the power of deception
Gold won't ever comfort me
The color of deception
