Pigments are used to color powdery substances. It is insoluble in water, grease, resin, organic solvent and other media, but can be evenly dispersed in these media and can make the media color, but also has a certain hiding power. The pigments for fine arts basically require the finer the particles, the better, the brighter the color, the better the lasting color (the better the stability). Watercolor paints are almost transparent except for white. Only in this way can we meet the needs of watercolor masking.
The gouache paint was originally invented by adding white powder to the watercolor paint to make the color opaque. Since the watercolor paint is transparent, it is difficult to modify it if it is wrong. The gouache pigment can be easily modified due to its opacity. Later, raw materials such as gum arabic were added to the gouache pigment to further improve its performance. Gum arabic can make the gouache paint dry and have a layer of gloss, but in special occasions that require flat coating (such as painting effect pictures and coloring animations), the glue will form irregular spots on the colored surface, or let the color Uneven, so there are special degumming pigments.
Oil paints are paints diluted with oil.
Chinese painting pigments are very rich, and there are various types, from mineral powder to plant extraction to animal extraction, the type is complex.
In theory, as long as there are three primary colors of red, blue and yellow, all other colors can be tuned out, but the purity of the tuned colors is always not high enough, so modern art pigment manufacturers produce high-purity pigments for various colors of hue and brightness To meet various needs. From the most basic 12 colors to the usual 24 colors or even 48 colors to more than sixty colors. Does not include special metallic colors.
Uses: It is an indispensable raw material for the manufacture of paints, inks, oil color pastes, cosmetic oil paints, colored paper, etc. It is also used for filling and coloring plastics, rubber products and synthetic fiber stocks.
