No complaints about your English, just pointing out that SOME people may
try to interpret that phrase differently, and that can lead to the sort
of issue that was being talked about. Asking about getting the 'default
background color' is a red flag, as it should never matter. If you are
setting the foreground color, you should have set the background color,
and thus not need to worry about the 'default'

Yes, if you could query this you could perhaps choose to theme your page
based on it, but then that really should be a very top level decision,
and after determining their 'default' you still set it in case you got
something wrong.
