For more information on this subject, please see the discussion on each of the composition principles.
Gouache

Graffiti Art
Refers to forms of art (or vandalism) where images or text have been spray-painted, sketched, or even scratched onto walls, sidewalks, or other publicly accessible areas.

Graphic Design
The applied art of arranging images and text to communicate a message. It may be applied in any media, such as print, digital media, motion pictures, animation, product decoration, packaging, and signs.

Grid Enlarging
The process of using a grid to enlarge an image; for copying very precisely, another image, on the same or a different scale, usually larger; used in scaling an image by drawing (see illustration). For more information on using this method, see the article titled “Using a Grid to Enlarge and Transfer an Image to Canvas.”
Grisaille
Monochrome painting generally employing shades of gray executed in a black pigment and an inert white pigment in oil, gouache, or tempera; a stained glass window incorporating muted tones as opposed to bright colors.
Guerrilla Art
Street art by Banksy.

A term often used interchangeably with “street art.” Guerrilla art is a form of art-making that entails installing unauthorized works of art in public places. This form of art expression allows the artist to express their views and opinions to a large audience anonymously. Such statements can be either political or merely to call attention to one’s surroundings. Guerrilla art differs from other forms of art. It is environmental and is not created on traditional supports such as a canvas. Such traditional art forms can be moved from gallery to gallery without any effect on the piece or its meaning; however, this is not so with street art. The surface to which street art is applied can be as fundamental to the piece’s meaning as the image itself.
