Description:
With a dark theme, spell check dialog is unreadable.

Similar issue was present in the formula editor in bug 90297, but was fixed previously. I'm mentioning it here since I think there is a more in-depth core issue here; parts defining default colors do not have a consistent background color in every place of the UI. I.e. in Options -> Libreoffice -> Colors: a default color for the text can be chosen. If left at automatic, this will be black, since it makes sense since the document (paper) background is most often white. However, this does *not* need to be same as the background of the UI. In the case of dark themes it is not. 

Still, this same color is being applied to the UI, at least in the spell checker. There may be other places where this is applied, too.

If I change this color from automatic to something else, the spell checking dialog can be readable, but this will also change the default (unformatted) color of the document text.

Suggestion: it should be made sure (and the dialog changed appropriately) this option is only used for document. UI color options should be separate and clearly marked as such.

Steps to Reproduce:
1. Choose a dark theme
2. Leave default document "text color" and "background" as is
3. open spell checking dialog

Actual Results:
Spell checking dialog background is dark (as expected), but document default color is used here for the text, which makes it unreadable.

Expected Results:
The dialog should be readable.

Document colors should be separate from document colors. LibreOffice should notice a dark theme and apply it's colors in all places of the UI, and/or have clear way to set these separately in the Options.
