What are the three colors in Chinese painting?

Cyanine and azurite belong to two main color systems in Chinese painting: plant pigment and mineral pigment, also known as watercolor and stone color respectively. Flower blue is water color, moist color, and can be dyed layer by layer. Azurite is stone-colored, colorful and thick. During the trial production of azurite, the colors of Touqing, Qing Er, Sanqing and Siqing were produced. The head blue that sinks at the bottom is darker in color, and the Siqing that floats on the surface is lighter in color. Usually in painting, watercolor and stone colors are not mixed.

The correlation is as follows

It's a substance, and its color is very close, but it can't be said to be a color.

Chinese painting pigments are divided into three categories;

Minerals, animals and plants are called stones, bluestone, bluestone, cinnabar and ochre are all minerals.

So is azurite. What about Sanqing? This should start with the production technology and method of making mineral pigments. Mineral pigments are collected, mined according to quality and ground to a very detailed degree. Adding water to precipitate, there are four containers. In the first container, the color of the upper layer is poured into the next one together with water, and then the sediment is poured into the third and fourth ones. In this way, the first container is called Touqing, and so on, the method and name are probably similar.
