Change color of background in "edit page" block editor (using white text)

Hello!

Do you have a fix / filter so that I can make the background color of the block editor to black?

I am using white text on my site set in customizer which makes it impossible to edit content in "edit page" as the text is set to white so its invisible.

I saw there was other themes that had fixed this with a filter / fix to the theme.

Thanks.
