If we do that, we must be prepared to use the light-background colors of the faces for printing even if the screen happens to be white-on-black. If people configure their back- and foreground for special effect, they might be surprised... However, as a default I agree that for printing (and paginated output is not likely to be used as the equivalent of a screenshot), a white background would appear a sensible default. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
