Being inert and unreactive, pure gold does not react with any acid except aqua regia. Thus its colour does not alter.

What color does gold turn when in contact with acid?
I'll assume you are asking about test acid. The test acid in gold test kits is nitric acid diluted to various strengths for use on different karat gold varieties. Here are a few scenarios to answer your question.Let's say you have a 14K gold ring. If you drip 14K acid on it, nothing will happen. If you drip 18K acid (or stronger) on it, the spot where the acid contacted it will turn brown. On the other hand, if the acid bubbles green, the ring is not actually gold at all.
