Hello Mr. Sharp and Keita,
I'm been lurking on this list for a few months and wanted to ask, why not
make a cmdline switch for gv to display a pdf's background and foreground
colors as something else?
That would have more applications then Keita's use case (although I agree
that setting the BG color from the latex source would be the correct
series of events in her case). I'm particularly thinking of a "dark theme"
as opposed to the normal white with black text type of idea.
Yes Mr. Sharp, I do know that pdf's have no exact FG or BG colors as you
pointed out earlier in the discussion, but something dumb and simple
should not be too hard to put together, right?
My idea is the equivalent of a user specified css file in html (which I
really should use more often): https://userstyles.org/

Thanks,
David
