We can associate this with the fact that the color blue is connected to royalty all around the world. Blue falls in between green and indigo in the visible color spectrum. The color pigment went through many trials but all of them failed. Many colorists were trying to obtain blue from purple by cutting the pigment and adding different acids. When artists tried to transform indigo into a form of blue, it always went straight to black. Azurite, which is a pigment gathered from the same plant as indigo, turned green-white when mixed with water. This ruled out the option of using this as a blue toned
