Export in green on a black background

Hello

I'm looking for a solution to export plans, in PDF, image or any other format readable by any "office" computer, with the following constraint: green line on BLACK BACKGROUND.

For green lines, no problem. On the other hand, for the black background, I struggle.

I tried to change the system colors, but it's not taken into account during the export. the background remains white.

Insert a black image into my plan? I haven't tried it yet but I'd like to avoid it.

Any other avenues?

Thank you in advance
