Inverting colors , importing Preferences template ?

Hi:

Still very new to LibreCAD.

I like to invert the background of canvas (workbench?).
Black is nice, but I like white for much better contrast.
How do we do that?
But this will affect all other objects like white lines that were in previous black background.

Is there a "theme" or "preferences template" with "white" canvas background that we can import
into LibreCAD?

Thank you.
