I want to know the answer to the following question:
What would to the carmine pigment if not used diligently?
All the background I'm provided with is that "The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant.". Is that enough to answer the question?
Answer: no
