Lines are one of the fundamental elements of design.
Lines can go in any direction. They can be used to show direction, divide space, and show emotion. Often people manipulate lines to enhance a design.
Shape
Lines and shapes go hand-in-hand. By connecting lines, shapes are created.
Color
Color is described by hue, value, and intensity. Hue is the color itself. For example, green, or purple. Value is the the lightness or darkness of the color. Intensity is the brightness or dullness of a color.
Texture
It is how something feels when touched, or looks like it would feel if it were touched.
Space
Where a shape or form occupies an area. It also refers to the background where we can make out the shape or form. It can be referred to as positive and negative.
Principles of Design
Rhythm
It is the flow of the design. Rhythm can be created by: repeating a color, shape, texture, line, or space, varying the size of objects, shapes, or lines in sequence, using a progression of colors from tints to shades, and shifting from one hue to another hue.
Proportion
It is the relationship between parts of a design. It also is a comparison of sizes, shapes, and quantities.
Emphasis
It is a point of interest. It draws your eye to a particular spot. There are different ways to create the emphasis principle such as: using a contrasting color, use a different or unusual line, make a shape very large or very small, use a different shape, or use a plain background.
Unity
When things look as though they belong together.
Balance
It is stability. There are three types of balance, symmetrical, radial, and asymmetrical.
