What is a Pigment?
A pigment is a powder that is completely or nearly insoluble and chemically unreactive in water or another medium, usually colored but sometimes colorless or fluorescent; in contrast, a dye is a colored substance that is soluble or goes into solution at some stage in its use.

Where do paint companies get their pigments?
However, most of the pigments used today are either synthetic organic or inorganic. Synthetic organic pigments are manufactured from coal tars and other petrochemicals. Inorganic pigments are made with the help of simple chemical reactions such as oxidation.
Where do modern paint pigments come from?
Synthetic organic pigments are derived from coal tars and other petrochemicals. Inorganic pigments are made by relatively simple chemical reactions—notably oxidation—or are found naturally as earth.
Inorganic pigments include white opaque pigments used to provide opacity and to lighten other colours.
Are pigment powders natural?
Natural Earth and Ocher pigments are all natural colors from the earth. They produce soft, semi-transparent colors with undertones that become apparent when mixed into opaque bases.
Their tinting strength will not be as strong or opaque as our oxide pigments, but their colors cannot be matched by man-made pigments.
How long does pigment powder last?
The pigment particles are charged by almost any visible light or ultraviolet light. The pigments then release energy in the form of visible light for 10 to as much as 24 hours.
Does pigment fade?
A field of interest that is prominent within the art and art history community is the determination of the photostability of different pigments.
As paintings grow older, the original color deteriorates causing fading and in some cases a complete change in color from the original work.
