What does contrast do in a design?

Contrast plays a crucial role in design as it helps to differentiate elements and improve readability. By using contrasting colors, shapes, sizes, or textures, a designer can draw attention to specific areas of a design, making it easier for viewers to understand the hierarchy of information presented. For example, text that contrasts sharply with its background becomes more legible, ensuring that important messages are communicated effectively. This differentiation is vital for guiding the viewer's eye across a layout, making it an essential principle for achieving clear and impactful graphic communication.

The other options touch on aspects of design but do not accurately reflect the fundamental function of contrast. While adding color to a design might be important, it does not describe the role of contrast specifically. Increasing file sizes and limiting color palettes are technical or stylistic choices that do not directly relate to the concept of contrast within the context of enhancing clarity and visual impact.
