[I already did this once way time ago- so I do not remember how to repeat this]
I recently inserted my own custom palette to
C:\Program Files\LibreOffice\share\palette
thus wanted to apply its colors to my documents. I can go to
Format > Page Style > Area > Color > Palette > [MY CUSTOM PALETTE]
and choose a color for a background - so far so good. But when I now press CTRL + P
I see black page instead of white- like I used to
I need to see white text on black background when I write and read on screen- and black on white when read on paper what I print out
