What is the difference between a dye and a pigment?
Pigments
There are two different types of pigments: Natural and Synthetic. Pigments are insoluble materials that are ground into a fine powder so that they can be suspended in a binder (usually an oil). Insolubility means that pigments can never be dissolved into the binder, the fine particles of the powder are suspended and stay solid in the binder. The binder surrounds the pigment particles and holds them in place.
Pigments produce paints that are more opaque than dyes and have low tinting strength. Opacity is the ability for paint to cover and hide another dried color that it has been applied over. Tinting strength is how well a color mixes with other colors. (Example: When mixing blue with white, how well does the blue disperse into the white? or How blue does the white look after the mixing?)
The first colorants that were used to create paint were naturally occuring earthen pigments. Prehistoric people used ochres and iron oxides to create images on cave walls in Lascaux, France. Many natural insoluble pigments are still used today in artists? paints. Metals are also natural insoluble pigments, like cadmium, titanium, and lead (very toxic).
