14k or higher gold will not notably react at all when exposed to nitric acid. Green reaction means low karat, and brown means 8-10k. You can also weigh the flakes and then do the regia method. After melting down the power or before, you can weigh it and take note of the difference. Then do math to determine what purity you had.

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.
