2.6: Key Terms
2-Dimensional Art : art that is executed on a two dimensional surface that has length and width; a flat (or nearly flat) surface. These include, but are not limited to, paintings, drawings, and prints.
3-Dimensional Art : art that is executed in the three dimensions of length, width, and height. These include, but are not limited to, sculpture, architecture, ceramics, glass, textiles, assembly, and installation.
4-Dimensional Art : art that is executed in, and depends upon, both space and time, which is considered the “fourth dimension.” Examples include but are not limited to performance art and video art.
Abstract Expressionism : or ABEX; this art historical term is specific to a group of painters working in New York after the Second World War. This group includes Jackson Pollock, Willem de Kooning, Lee Krasner, and Helen Frankenthaler. Their primary approach to painting was gestural, and “all over,” a condition in which no single part of the work is visually predominant.
Acrylic : a fast drying water-soluble petroleum based painting medium.
Actual Texture : the condition in which texture is created, not represented. Actual texture is the opposite of simulated texture or the illusion of texture. Examples include brushstrokes, impasto, collage, and inclusion.
Additive Color : color based on projected light.
Additive : a sculptural process in which material is added.
Afterimage : the optical sensation that occurs after a visual stimulus is removed. The afterimage is a quickly fading complement of the original stimulus.
Analogous Color : a color scheme that uses colors adjacent to an initial point on the color wheel. For example, if an artist chose red for the initial color, then an analogous color scheme would employ the color range that occurs between orange, red, and purple.
Armature : a wire or wood substructure used to support a clay sculpture while it is being worked.
Assembly : a sculptural process in which disparate materials are combined to form the final artwork.

Lithograph : a printing process that relies on the repulsion between oil-based ink and water. A stone (or aluminum plate) is drawn on and etched. Where the stone is etched will absorb water. Where the stone is not etched (protected by the drawing or image) the stone will remain dry. Water is applied to the stone. Ink is then rolled over the stone. Where the stone is wet, ink is repelled. Where the stone is dry, ink adheres. Paper is then pressed onto the inked stone resulting in a print.
