| color | The visual sensation dependent on the reflection or absorption of light from a given surface. The three characteristics of color are hue, value, and intensity. |
| form | A three-dimensional volume or the illusion of three dimensions (related to shape, which is two-dimensional); the particular characteristics of the visual elements of a work of art (as distinguished from its subject matter or content). |
| line | A point moving in space. Line can vary in width, length, curvature, color, or direction. |
| shape | A two-dimensional area or plane that may be open or closed, free-form or geometric. It can be found in nature or is made by humans. |
| space | The emptiness or area between, around, above, below, or contained within objects. Shapes and forms are defined by the space around and within them, just as spaces are defined by the shapes and forms around and within them. |
