Why is contrast considered an effective tool in design?

Contrast is considered an effective tool in design because it introduces sudden changes that capture attention. This principle utilizes differences in color, size, shape, and other visual elements to create a striking distinction that helps guide the viewer's eye and emphasizes important components of the design. By juxtaposing contrasting elements, designers can highlight a focal point or create visual interest, making the overall composition more dynamic and engaging.

This technique helps to break monotony and allows viewers to quickly identify key areas or messages within the design. For example, using dark text on a light background can enhance readability and attract attention to specific information. In essence, contrast serves as a visual tool that can enhance clarity, drama, and the effectiveness of communication within design.
