Yes, that's what I do at the moment and it works fine for monochrome
output.

But if the buffer has colored text and I do not want monochrome output,
how should those colors be chosen?  I do not think that swaping black
and white and keeping all other colors intact would give good results.
And I do not think there is a formula to reverse video colors, or is
there?
