I want to know the answer to the following question:
What would verdigris do to other colors that it came in contact with?
All the background I'm provided with is that "Verdigris is made by placing a plate or blade of copper, brass or bronze, slightly warmed, into a vat of fermenting wine, leaving it there for several weeks, and then scraping off and drying the green powder that forms on the metal.". Is that enough to answer the question?
Answer: no
