When applying a theme, what aspect of the presentation is typically changed?

When applying a theme to a presentation, the primary aspects that are modified are the color scheme and fonts. Themes are designed to create a cohesive and visually appealing look throughout the entire presentation. By changing the color scheme, a theme can set the tone or mood of the presentation, affecting how the audience perceives the information being presented. Similarly, fonts are adjusted to maintain consistency in style and readability across all slides, ensuring that the presentation is polished and professional.

While text size, slide numbers, and image placement can vary based on the content of the presentation, they are not inherently altered when a theme is applied. Text size may remain the same or be adjusted for specific slides, slide numbers are often added independently of the theme, and image placement is determined by the presenter based on individual design preferences rather than the theme itself. Therefore, the modification of the color scheme and fonts is the fundamental change that occurs with the application of a theme in a presentation.
