Use the application-level background setting when the default theme color does not fit your design.

Change the background color

Open the application in the Designer and select Settings.
In the User Interface settings, enable Overwrite Background Color.
Select Edit Background Color and choose the required color.
Save the application settings.

Preview the application to confirm that the color is applied behind the page content. Check pages with short content as well as longer pages, because the background is most visible in unused areas of the runtime window.
