elements of design
The basic visual parts artists use to build an art work: line, shape, form, space, colour, texture and value.
principles of design
The ways artists arrange the elements: for example balance, contrast, emphasis, movement, proportion, rhythm and repetition, unity and harmony, and variety.
line
A mark made by a moving point, longer than it is wide. Lines can be actual (drawn) or implied (suggested).
implied line
A line the viewer's eye "connects" even though it is not drawn, such as the direction of a pointing finger or a row of dots.
line weight
How thick, thin, dark or light a line is. Varying the weight makes a drawing more lively.
shape
A flat, two-dimensional area with height and width, made by a line or a change in colour, value or texture.
geometric shape
A regular, measurable shape such as a circle, square or triangle.
organic shape
An irregular, free-flowing shape like a leaf, a puddle or a cloud.
negative space
The empty space around and between the subjects of an art work; the subjects are the positive shapes.
contour drawing
A drawing that follows the outer and inner edges of a subject with a slow, continuous line.
