Ternary plot of different colors of Ag–Au–Cu alloys. Colored gold is the name given to any gold that has been treated using techniques to change its natural color. Pure gold is slightly reddish yellow in color, [1] but colored gold can come in a variety of different colors by alloying it with different elements.
Electrum is a naturally occurring alloy of gold and silver, [1] [2] with trace amounts of copper and other metals. Its color ranges from pale to bright yellow, depending on the proportions of gold and silver.
It can be used on copper and its alloys, silver, nickel, iron, gold. The color depends on the duration of immersion, the sequence of colors on brass: Golden yellow-copper-purple-dark, blue-light, blue-chrome-nickel-red-grey, blue, and gray-black to iron or carbon steel. [32]

Gold readily dissolves in mercury at room temperature to form an amalgam, and forms alloys with many other metals at higher temperatures. These alloys can be produced to modify the hardness and other metallurgical properties, to control melting point or to create exotic colors. [10] Gold is unaffected by most acids.
Shakudō (赤銅) is a Japanese billon of gold and copper (typically 4–10% gold, 96–90% copper), one of the irogane class of colored metals, which can be treated to develop a black, or sometimes indigo, patina, resembling lacquer.
Oroide is copper and zinc, or copper and tin, often employed inexpensively for decorative purposes where a gold-colored metal is desirable. Oroide may refer to: Brass, an alloy of copper and zinc that has a bright gold-like appearance; Bronze, an alloy of copper and (in modern times) tin; Other gold-colored copper alloys
