I want to know the answer to the following question:
When did Egyptians start to make red pigment?
All the background I'm provided with is that "The Egyptians used the root of the rubia, or madder plant, to make a dye, later known as alizarin, and also used it to color white power to use as a pigment, which became known as madder lake, alizarin or alizarin crimson.". Is that enough to answer the question?
Answer: no
