Copper and gold look similar, but while gold is yellowish, copper is reddish.
Pure gold is typically a yellow color, but certain alloys of gold can have a reddish or coppery hue. This is achieved by mixing gold with other metals like copper or silver to create different shades of gold. So, while gold itself is not naturally copper-colored, it can be modified to appear that way through alloying.
Rose gold is a metal alloy made by mixing yellow gold with copper and sometimes silver. It gets its pink hue from the copper content. Rose gold is durable and typically has a higher copper content than yellow or white gold. It is known for its romantic and vintage look.
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
The solute in an 18k gold ring is typically gold, which is mixed with other metals like silver, copper, and zinc to create the alloy.
Some metals that are not silver gray in color include gold (yellow), copper (orange-red), brass (yellow-brown), and bronze (reddish-brown).
Some examples of metals that look like copper include brass, bronze, and rose gold.

They look like a shiny gold. But they are copper. So don't flip out. The most produced one is the 1797-1801.
A pfennig is a German "penny" and would not have gold in it. Would normally be brass or copper. If shinned up can look much like gold

Pure gold is typically 99.9% gold, with the remaining 0.1% usually composed of trace elements like copper. So in a typical gold alloy, copper content can range from around 5-10% depending on the specific composition.
Gold stones look like regular stones with spotspots of gold
I would like to sale two bit coins. Gold and copper color
A copper sheet is made of... surprise... copper. No gold.
