Painting is a visual art, which is characterized by the practice of
applying paint, pigment, color or other medium to a solid surface
(called "matrix"[1] or "support").[2] The medium is commonly applied to
the base with a brush. Other implements, such as palette knives,
sponges, airbrushes, the artist's fingers, or even a dripping technique
that uses gravity may be used. One who produces paintings is called a
painter.
