Vertex Painting is a simple way of painting color onto a Grease Pencil object, by directly manipulating the color of points/vertices, rather than use only the materials base color.
When a point is painted, the color of the points is mixing with the base material color according to the settings of the brush.
A vertex in Grease Pencil is called point. Point and vertex names are equivalent.
