Vim tries to obtain the background color from the terminal by sending
t_RB. So first check if t_RB is set.
This doesn't happen right away, thus Vim may first draw the windows
before the response comes. Then Vim will redraw if needed. You can
find the response in v:termrbgresp. You could set a timer to check for
the value and act accordingly. Or use an OptionSet autocommand to
trigger on 'background' changing.

Vi is clearly superior to emacs, since "vi" has only two characters
(and two keystrokes), while "emacs" has five. (Randy C. Ford)
