How can you customize the appearance of a Power BI report?

• A. By embedding external images into the report visuals
• B. By creating a custom theme file with specified colors, fonts and formatting
• C. By applying pre-defined color schemes and fonts
• D. By adjusting the data sources within the report

Answer: (B)

Customizing a Power BI report’s appearance is best done with a theme file. A custom theme is a JSON file that defines the color palette, fonts, and formatting rules Power BI applies across visuals and pages, so you get a consistent look that matches branding. By importing this theme, you set default colors for charts, fonts for titles and labels, and other formatting so every element follows the same style without tweaking each one individually. This approach is more comprehensive than embedding external images, which only affect specific visuals, and more flexible than using only the built-in pre-defined schemes that may not align with your branding. Changing data sources affects what the report shows, not how it looks.
