Asked in Gold and Precious Metals
Is there a liquid that will change color when it comes in contact with gold?

I doubt it. Color-change is an indication of a chemical reaction. Gold, however, is generally non-reactive (although highly conductive), which is why it doesn't tarnish or rust. Since I cannot think of another chemical gold reacts easily with, I'm giving a tentative "no" to your question.
