Azurite is a natural blue basic copper carbonate, Cu3(CO3)2(OH)2. The color of the small particles depends very much on their size and their surface structure.The special Japanese elutriation treatment ensures a more exact and equal grain size than just by sieving, this make the colors more brilliant. https://www.kremer-pigmente.com/en/shop/pigments/1673110-azurite-gunjyou-no-10.html

mixed metal oxide Y In Mn
Mas Subramanian’s lab has created other colors using YInMn chemistry, including purple, yellow, orange and green. They created yellow and orange by replacing iron for manganese we have made; green by switching copper for manganese; and purple by swapping indium with titanium and zinc.
