What is the significance of using a dark font on a white background?

Using a dark font on a white background significantly enhances readability, which is crucial for effective communication. This high contrast between the text and the background allows for clear visibility, making it easier for readers to process the information quickly. The human eye naturally finds it easier to read dark text on a light background, which minimizes strain and increases comprehension, particularly for lengthy documents or detailed information.

In contrast, other options such as increasing artistic appeal, conserving ink, or making the text bold do not directly address the core purpose of readability. While aesthetic considerations and efficiency in ink usage can be valuable in different contexts, the primary function of the contrast between a dark font and a light background is to facilitate clarity and ease of reading for the audience.
