What does pattern refer to in design?

In design, the term "pattern" specifically refers to a repeated decorative design that is visually organized and intentional. Patterns can be found in various forms such as textiles, wallpaper, flooring, and graphic design, where they create visual interest and consistency. Patterns can serve different functions, such as enhancing aesthetics, conveying themes, or creating rhythm within a design. This repetition can involve shapes, images, or motifs arranged in a systematic way to produce an overall effect that can be recognized and appreciated.

Other options describe different concepts that do not align with the definition of pattern. A random arrangement of elements suggests a lack of structure, which negates the idea of a pattern's repeated nature. A sequence of colors, while it may imply use in design, does not encompass the broader concept of a decorative design that can include shapes and forms. Lastly, a shape with three dimensions refers to a specific geometric characteristic, rather than a repetitive design element. Therefore, the choice of a repeated decorative design accurately captures the essence of what constitutes a pattern in design.
