Which of the following practices should be avoided to enhance readability in presentations?

Using light text on a light background significantly hinders readability in presentations. This practice creates insufficient contrast, making it difficult for the audience to see and comprehend the content. Effective presentations rely on clear visibility, which is best achieved through strong contrasts between the text and background colors. For instance, dark text on a light background or vice versa is generally recommended because it enhances clarity and helps convey the message more effectively.

In contrast, other practices such as using contrasting colors, selecting readability-focused fonts, and maintaining a clean layout are all essential components of effective presentation design. Contrasting colors make information stand out, readability-focused fonts ensure that the audience can easily read the text, and a clean layout allows for better organization and flow of information. These elements collectively contribute to a more engaging and understandable presentation, while light text on a light background detracts from those goals.
