A pigment is a special kind of chemical compound that gives color to things. It makes something look a certain color. Unlike dyes, which dissolve in water, pigments stay in place and do not dissolve easily. They are usually made from inorganic materials.

Fun Facts About Pigments

People have used natural pigments for a very long time. They used colors like ochre, charcoal, and lapis lazuli to paint and decorate long ago. These colors came from the earth and stones and were very valuable. Today, pigments are still important in art, industry, and even in nature.

In living things, biological pigments give color to plants, animals, and other organisms. These pigments help protect living things, attract others, or even help them capture energy from the sun. Whether natural or made by people, pigments play a big role in the world around us.

How Pigments Work

Pigments give color because they take in some colors of visible light and let others show. The way the material is put together decides which colors are taken in and which are shown. The light that shows gives us the color we see.

People have used minerals as colorful paints for thousands of years. Early humans painted their bodies and made cave art with natural pigments like ochre, which comes from iron oxide. Blue paint was made from a stone called lapis lazuli, and other colors came from places like Siena and Umbria.
