Paint

In Art and Industry a paint is a liquid that is used to apply color to an object.

In the construction industry and manufacturing industries one of the purposes of paint is to apply a protective envelope to objects. Many early paints combined an oil with a volatile component, with colourful oil soluble liquid dyes, or with finely divided colourful powders, known as pigments. After the volatile components of the oil evaporated, the non-volatile portion of the oil stuck to the object's surface, binding the colour to the surface. Early paints could be quite durable.

Artists would bring a palette of multiple colours of paint, to an artwork, and then mixing them.

Artists also use water-based paints.

Some modern paints have to be activated, before they Bond with a surface. That activation can be through the application of heat, electricity, or from a chemical reaction.

Traditionally paint was applied with a paintbrush, a stick with a tuft of animal hair, which would hold a quantity of paint, while it was being applied. Some modern brushes substitute the animal hair with artificial fibers. Paint-rollers are also used to apply paint. And modern devices apply paint as an aerosol.
