Dear,
I'm confident that it is possible to change the background color of the
panel using the Theme Editor of the SAP NetWeaver Portal. For that,
please open your custom theme "Theme Name" in the Theme Editor and
navigate to:
> Group and Container Controls
> Panel
> Content Area of Panel
> Color of Emphasized Background
Kindly change the color code to your liking, e.g. #fff for white. Press
"Save" to submit your changes and patiently wait while the stylesheet ofyour custom theme is re-generated. Please clear the browser cache
afterwards and re-test. The background color of the panel should have
changed to the previously chosen color.
Thanks & Regards ,
Meghal Shah
