Variety is a principle of design that refers to a way of combining visual elements to achieve intricate and complex relationships. It is a technique used by artists who wish to increase the visual interest of their work. Artwork that makes use of many different hues, values, lines, textures, and shapes reflects variety. Keeping the same size while changing the color can also show variety.
Although varying the components of a design can create visual interest and avoid monotony, design elements must also convey a sense of cohesion. It is important to maintain cohesion or the design will look like a mess of mismatched images thrown together. Still, visual design without any variation is boring.
