Which of the following is NOT an element of design?

The correct answer is 'theme' because it is not considered a fundamental element of design. In design disciplines, elements are the basic components that make up a piece of artwork or design piece, such as colour, shape, size, and texture. Each of these elements plays a critical role in visual composition and contributes to how the viewer perceives and interacts with the design.

Colour involves the hues used in a design and can affect mood and emotion; value refers to the lightness or darkness of a colour, which can create depth. Shape and size contribute to the overall form and volume of an object within a design, influencing balance and structure. Texture adds the tactile quality of a surface, affecting both the visual appearance and the sensory experience of a viewer.

On the other hand, 'theme' refers to the overarching idea or concept behind a design, which is more abstract and interprets the elements rather than functioning as a base component itself. While a theme can guide the use of the other design elements, it is not an inherent part of the visual structure or physical attributes of the design.
