The following picture shows the mineral pigments used in Chinese paintings:

The need for colors to be vibrant for a long time without fading is the focus.

Chinese painting pigment should use mineral pigment, that is, heavy color painting, brushwork heavy color, splash color are using mineral pigment. Mineral pigment is the so-called stone color, is extracted from the ore color, ore color is very deep, color quality is pure, heavy color painting is to use mineral color to create, mineral color color is very stable, because of the characteristics of its ore can withstand light exposure and climate change, because some natural raw materials contain a certain degree of toxicity, natural pigments should also be used with caution.

Western oil paintings in ancient times with egg whites and paints made by the painter, it is said that the pigment raw materials also include red and blue and other colors of gemstones, animals, plants, natural pigments containing parts to make pigments.

Ancient charcoal drawings (sketches, etc.), the main ingredient is carbon, carbon's chemical properties are very stable, it is not easy to chemical reaction with other elements. So the ink writing or drawing can be preserved for a long time without discoloration, this point is the same as the Chinese black and white ink, carbon is the main constituent element of ink, carbon is chemically stable at room temperature is the main reason why the ink drawing does not change color for a long time.

And some other traditional handmade paintings they basically use pigments from natural sources, as mentioned above.
