The elements of art are the building blocks used to create a work of art. They are: Line, Shape, Form, Color, Value, Texture and Space.
A line is an identifiable path created by a point moving in space. It is one-dimensional and can vary in width, direction, and length. Lines often define the edges of a form. Lines can be horizontal, vertical, or diagonal, straight or curved, thick or thin. They lead your eye around the composition and can communicate information through their character and direction.
Shape has only height and width. Shape is usually, though not always, defined by line, which can provide its contour. There are two main types of shape / form: geometric and organic. Geometric shapes and forms include mathematical, named shapes such as squares, rectangles, circles, cubes, spheres, and cones. Geometric shapes and forms are often man-made. However, many natural forms also have geometric shapes. Organic shapes and forms are typically irregular or asymmetrical. Organic shapes are often found in nature, but man-made shapes can also imitate organic forms.
Form has depth as well as width and height. Three-dimensional form is the basis of sculpture and decorative arts. Just like with shapes, forms are either geometric or organic. Adding depth to a shape makes it a form. For example, a triangle is two-dimensional and is a shape, but a pyramid which is three-dimensional, is a form.
Color has three main characteristics: hue (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is). Color is a unique language with its own vocabulary. Just like words, color emits emotional energy. The meaning can be changed completely, simply by changing the tone or intensity. Every hue, tint, shade and tone influences our thinking and makes us react in some way. When selecting color schemes, think about how the palette makes you feel and about how you want your viewer to feel.
Value describes the brightness of color. Artists use color value to create different moods. Dark colors can often convey a sense of mystery or foreboding. Light colors often describe a light source. The terms shade and tint refer to value changes in colors. In painting, shades are created by adding black to a color, while tints are created by adding white to a color.
Texture is the surface quality of an object that we sense through touch. Artists can also convey texture visually in a two-dimensional work of art. Texture gives a visual sense of how an object depicted would feel in real life if touched: hard, soft, rough, smooth, hairy, leathery, sharp, etc. Repeating a line or shape is one way to imply texture.
Space in a work of art refers to a feeling of depth or three dimensions. It can also refer to the artist's use of the area within the picture plane. The area around the primary objects in a work of art is known as negative space, while the space occupied by the primary objects is known as positive space.
