Microsoft has announced a new feature for business users using Power BI application for report creation, the new theme gallery. This gallery is a dedicated place for you to share and find new themes for use in your Power BI reports.
Theming is a new preview feature in the Power BI Desktop that lets you pick colors to use in your charts and to show in the color palette. This feature is a great way to quickly incorporate your company branding or a little personality to your reports. To add a theme to your report, you import a JSON file listing all the colors you want to use in your report’s charts.
You can learn more about the theming feature in the recent March Desktop release blog post.
