What are pigments?
Pigments are substances that are responsible for giving colour to an object. We know that the primary colours of light are red, green, and blue. The ptimary colours of pigment are different- they are red, blue, and yellow. Secondary colours are produced by mixing the primary colours.
Pigments are found both in the living world and in man made materials. The natural pigment present in a living organism plays a very crucial role in its daily life. The most common pigment present in human and animal's skin is known as melanin, which gives protection from sunburn.
The earliest pigments used by people were those that occurred naturally, such as ochres and iron oxides which have been used as colorants. Today, synthetic pigments are widely available.
