Hi,   We have a need to change a theme once published.  The idea is to be able to change a black background to white or NONE, and change the white font to black just before hitting the print button.

I know there are copy formatting options while working on the dashboard(s), before it's published, but I can't figure out how to set it up so that once it's published and the user views the dashboard, he/she can now "hit" a toggle of some sort, changing the black background to white and change the white fonts to black.

They will be printing to a PDF.

Thanks and let me know.
