Stippling is the creation of a pattern simulating varying degrees of solidity or shading by using small dots. Such a pattern may occur in nature and these effects are frequently emulated by artists.
In a drawing or painting, the dots are made of pigment of a single colour, applied with a pen or brush; the denser the dots, the darker the apparent shade—or lighter, if the pigment is lighter than the surface. This is similar to—but distinct from—pointillism, which uses dots of different colours to simulate blended colours.
