Pigmentation in paint is the process of adding color to a painting. Pigment is a dry powder that is mixed with a binder, such as oil or water, to create a pigment paste. The paste is then added to the paint base and mixed until it reaches the desired color.
Pigments can be made from a wide variety of materials, including minerals, plants, and even insects. The most commonly used pigments are made from titanium dioxide, iron oxide, and carbon black. These pigments are able to produce a wide range of colors, including white, black, brown, red, orange, yellow, green blue, and purple.
In addition to providing color to paintings, pigments can also add texture and depth. For example, by adding different types of pigments to a painting you can create an effect known as impasto where the paint appears thicker and more textured.
If you are interested in experimenting with pigmentation in your paintings then there are many ways to do so. You can buy commercially available pigment pastes or make your own at home using natural materials like fruits and vegetables. There really is no limit to what you can create so have fun exploring!
