The paints used by the first people were a mixture of metal oxide, clay soil, and sap of some plants. These substances are thought to be applied to various surfaces by mixing with water. In ancient Egypt, for example, glue was mixed into the paints to impart shine and strength, and they were coated with wax to protect the paints from the influence of the air.

In general, the dyes are inorganic, but the dyes used in the textile sector are organic. Some of the dyes are of natural origin, but most are synthetic. Many of these are obtained by chemical synthesis processes.

Paints are applied on the surface of the goods in order to protect the goods from external influences and to have a beautiful appearance. Paints do not make any changes except to give color to the surface to which they are applied. If they are scraped, they leave the surface. Dyestuffs are substances which give color by creating attraction with spontaneous or suitable reagents.
