Line is the path of a point moving through space.
Shape / Form
Shape implies spatial form and is usually perceived as
two-dimensional. Form has depth, length, and width and resides in
space. It is perceived as three-dimensional.
Color
Colors all come from the three primaries and black and white. They have three properties – hue, value, and intensity.
Value
Value refers to relative lightness and darkness and is perceived in terms of varying levels of contrast.
Texture
Texture refers to the tactile qualities of a surface (actual) or to
the visual representation of such surface qualities (implied).
Space / Perspective
Space refers to the area in which art is organized. Perspective is
representing a volume of space or a 3-dimensional object on a flat
surface.
Pattern
Pattern refers to the repetition or reoccurrence of a design element, exact or varied, which establishes a visual beat.
Rhythm / Movement
Rhythm or movement refers to the suggestion of motion through the use of various elements.
Proportion / Scale
Proportion is the size relationship of parts to a whole and to one
another. Scale refers to relating size to a constant, such as a human
body.
Balance
Balance is the impression of equilibrium in a pictorial or sculptural
composition. Balance is often referred to as symmetrical,
asymmetrical, or radial.
Unity
Unity is achieved when the components of a work of art are perceived as harmonious, giving the work a sense of completion.
Emphasis
Emphasis refers to the created center of interest, the place in an artwork where your eye first lands.
