There are, however, places in the world that allow the claim of 24kt. to alloys with as little as 99.0% gold ("2 Nines Fine" or "Point Nine-nine Fine). An alloy which is 14 parts gold to 10 parts alloy is 14 karat gold, 18 parts gold to 6 parts alloy is 18 karat, etc. This is becoming more commonly and accurately expressed as the result of the ratio, ie: 14/24 equals .585 (rounded off), and 18/24 is .750 ("Seven-fifty Fine").

There are hundreds of possible alloys and mixtures possible, but in general the addition of silver will color gold green, 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.
