Abstract art refers to all types of artwork, such as paintings, sculptures, etc, that are interpreted using references outside of an objective perspective or reality. This departure from reality is indicated in imagery and style. Departures can be slight, partial, or complete. Abstraction exists along a continuum. Even art that aims for verisimilitude of the highest degree can be said to fall into this category. Artwork that contains abstract elements, for instance, altering color and form in ways that are initially obvious, can be said to be partially abstract. Art that is fully abstract bears no trace of any reference to anything recognizable.
