Which design principle emphasizes the importance of visual hierarchy?

The design principle that emphasizes the importance of visual hierarchy is contrast. Visual hierarchy is about arranging elements in a way that clearly signifies their order of importance, guiding the viewer's eye to the most critical parts of a design first. Contrast plays a crucial role in establishing this hierarchy by differentiating elements through variations in color, size, shape, or texture. By making certain elements stand out more than others, contrast helps viewers quickly grasp the focal points of a design.

For instance, using a bold, bright headline against a muted background allows the headline to draw immediate attention, while less prominent text can be styled in a lighter color or smaller size. This strategic differentiation ensures that viewers understand what to focus on, enhancing readability and overall communication effectiveness in the design.
