ELI5-is there any chemical solution or process that would discolour gold to the point where it would look like lead?

Question

Long story short-this is research for a piece of fiction. Is there any chemical or reaction, even if otherwise pointless, that would achieve this, besides just painting the gold?

Answer 1

No.Gold is too chemically inert to produce colourful oxides like aluminium, titanium or arsenic and anything reactive enough to effect gold also dissolves the metal or forms an amalgam like mercury.
