What design principle is essential for creating legible text?

Contrast is essential for creating legible text because it directly affects how easily the text can be read against its background. High contrast between the text color and the background color enhances visibility, making the text stand out and easier to decipher. For example, black text on a white background or white text on a dark background provides strong contrast, which significantly improves readability.

In design, contrast can be influenced by factors such as color differences, font weights, and sizes. Adequate contrast not only helps in legibility but also ensures that the information is accessible to a wider audience, including those with visual impairments. Effective use of contrast not only enhances legibility but also contributes to the overall aesthetic of the design, guiding the viewer’s attention and improving the user experience.
