Line: a continuous mark made on a surface with a pointed, moving tool. Lines can have different lengths, widths, textures, directions, and degrees of curve. They are considered one-dimensional and are measured by length.
Shape: two-dimensional and encloses space. The two dimensions in a shapre are height and length. (2D = H & L) Shapes are either geometric or organic.
Value: Deals with the lightness and darkness of a color (or pencil) Value depends on how much light a surface reflects. Value is also one of the 3 properties of color.
Form: 3 dimensional and encloses space. The 3 dimensions in a form are height, length, and depth. (3D = H & L & D)The space inside an object is called the positive space and the space outside of the object is negative space.
Texture: refers to how things feel or how they look like they might feel on the surface. Texture is perceived by sight and touch. Objects can have rough or smooth textures. They can also have matte or glossy surfaces.
Space: refers to the emptiness or area between, around, above, below or within objects. Shapes and forms are defined by space around and within them. 3 ways to show space are: Overlapping, between, and the use of perspective.
Color: is derived from reflected light. The sensation of color is aroused in the brain by response of the eyes to different wavelengths of light.
