High Contrast and no accessibility options changes the colors of the cells themselves unless they’re highlighted. Is there any way to invert the color for my view, not actually changing the color of each cell? Thank you.
- Press F11
- The styles and formatting section will appear
- In this section, right-click “Default” and choose “Modify”
- Go to tab “Font Effects” and set “Font color” to white
- Go to tab “Background” and choose color black (it’s on the top left)
- Click the big ‘OK’ button
- Go to the menu: File → Templates → Save as template
- Save the template as (for example) “My Default Template”
From now on you can use this template to create a new spreadsheet in black and white.
Hope this helps.
Also, Tools > Options… > LibreOffice > Application Colors (v5.1) / Appearance (prior versions) > Custom Colors section > under General > change (reverse) Document background and Font color entries. This UI change is possibly less desirable though that using styles+template.
If you don’t mind building from source code, you can use XRandR-invert-colors:
I prefer white on black pretty much everywhere, and until I found this utility, I was pretty frustrated by not just LibreOffice but also Firefox, neither of which obey the “high contrast invert” theme I had set on my Debian Mate desktop.
