Re: Strange color behaviour with seminar
I apologize for taking so long to respond. I wanted to test on several
different computers first. I concocted an example. When I
process this (using pdflatex) on my somewhat aged PC, all of the rules in
the table, and also the fraction bar in the displayed equation, come out
in green. The text is in blue. When I try the same experiment on a newer PC,
the lines do look blue. Furthermore, I see the same results when I simply
use the color package (without texpower at all) and set the text color to
[rbg]{0,0,0.5}.
So I now believe that this
phenomonon has more to do with the graphics adapter than with any tex
code. This probably is true for others who are seeing these wierd colors.

Indeed when I check out the smooth text and images in acrobat reader the footrule
turns blue
but the fonts are ugly
is it a bug in acoread?

Unfortunately, your code is far from providing a working
example of the effect you mention.
If I extend it like this:
\documentclass[a4]{seminar}
\usepackage{color}
\usepackage{pifont}
\input{seminar.bug}
\input{seminar.bg2}
\usepackage[colorlinks,urlcolor=red]{hyperref}
\usepackage{fixseminar}
\PassOptionsToPackage{lightbackground,sans,fixcolorstack}{texpower}
\usepackage{texpower}
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\headrulewidth}{2pt}
\renewcommand{\footrulewidth}{2pt}
\begin{document}
\begin{slide}
test
\newslide
test
\end{slide}
\end{document}
and compile with latex+dvips+distiller, then everything is
blue as expected. When I compile with pdflatex, then everything
on the first page is blue as expected, and on the second page
everything (including body) is black.
This is a problem ultimately caused by the fact that seminar's
output routine stems from the stoneage of LaTeX, when the
color package didn't exist.
Using the current development version of powersem (attached)
instead of seminar will cure this somewhat, because it defines
a patched output routine. But you have to leave out
\input{seminar.bug}
\input{seminar.bg2}
because they will overwrite powersem's changed output routine.
powersem loads these anyway before applying the patch.

As I said, for my example it's black. Could you post

> sometimes the rule in array are brown to
Are you sure this isn't a `trick of the light' or some
anti-aliasing effect? Did you look with maximal
magnification?
If yes, please post a complete (minimal) test example.
> I got this with or without the option lightbackground, fixcolorstack
These shouldn't have any influence here, unless
you're using dvips.

Re: Strange color behaviour with seminar
I see similar problems in my use of texpower with the seminar style. In
fact, all of my rules (for example, in tables) come out in green. (I'm using the
default
background). As near as I can figure the green is the "mathcolor" for the
whitebg. However, since I am not using the colormath option, nothing in
math mode is coming out in green.
For the lightbackground, the mathcolor is either some kind of green (in
ordinary and enhanced mode) or {.7,.8,.7} (rgb value) in dimmed mode.
Maybe that is the brown you are seeing.

Strange color behaviour with seminar
Hi,
I'm trying to use texpower to make my presentation ... It's a great
tool.
But I've got some strange color problems with texpower + the seminar
class
My latex preamble looks like this:
\documentclass[a4]{seminar}
\usepackage{color}
\usepackage{pifont}
\input{seminar.bug}
\input{seminar.bg2}
\usepackage[colorlinks,urlcolor=red]{hyperref}
\usepackage{fixseminar}
\PassOptionsToPackage{lightbackground,sans,fixcolorstack}{texpower}
\usepackage{texpower}
...
with the fancyheadings package the header (text and rule) is in black
(!?)
and the footrule is brown (it should be blue)
sometimes the rule in array are brown to
I got this with or without the option lightbackground, fixcolorstack
what's wrong?
