[preview-latex-devel] color support/non-support

[David K. <da...@gn...>]

Hello all,

I am pondering what to do with colors.  Clearly, the thing I did in
the 0.7.8 release (removing the appropriate color wrappers when
shipping out) was not the wisest choice: it helps somewhat with
preview-latex, but it causes surprising effects when preview.sty is
used standalone.

So the question is how intrusive the colors from the Emacs window
should turn out.  If the document contains no color support, it is
reasonable to press fore- and background colors onto the preview.

But if they do?  For example, if we are doing some prosper slides
with some fancy color selection scheme, the previews should probably
reflect that instead of trying to blend in with the text.  Unless
only small pieces of math are previewed instead of whole slides.

Unfortunately, with color.sty loaded, there is little possibility of
detecting an intentional vs a default black-on-white coloring scheme.

Before trying to implement something definitely, what are your
thoughts?  One thing at least seems more or less clear: when we are
tampering with the foreground color, we should try tampering with the
background color in the same way.  White-on-black Emacs users should,
if feasible, not have to deal with black-on-black previews...
