You can do it with CSS. But it has changed a bit for 3.20. You may
compare this thread:

Well, that was not for label widget, but for tooltip. But label widget
should behave similar. And with similar code I once set foreground and
background for button widgets -- I had that working for 3.18, but I
have not yet fixed that for 3.20. (https://github.com/ngtk3/nim-gtk3/bl
