I'm not sure where they got it. The wealth and the nobles of the Renaissance, however, would use a dye made from kermes and cochineal to make brilliant red clothing.
Yes, back in the renaissance, they used it for nobles and wealthy.
My favorite color is red. Red is at the end of the spectrum of light. It's with orange and opposite of violet. I didn't know that. What else do you know about red? It's actually a primary color for the RGB and CMYK color model. I learned about primary colors in school when I was little. Great! In addition, the planet Mars gets its red color from iron oxide. I wish we could travel to Mars. In fact, red was among the first colors prehistoric artists used, from ochre. I guess they got red pigment from the dirt or something.
In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal.
