In painting, medium is the term used for the substance that binds the pigment in paint. Synthetic substance is used in acrylic paint, natural oil for oil paints, and egg yolk for tempera.
The word "medium" can also be used to change the paint's consistency, or to describe a category of painting or merely the type of paint used.
