How to change text of dialog box?

[IndustrialOne]

Windows Version: <<Windows 10 Pro 21H1 19043.906, ...>>

Question How do I change the text in the dialog box? In the theme I have it is black but it should be white.

Things you already tried I changed all black colors to white but it remained the same.
