[pdftex] hunting strange colour behaviour in pdftex

[Steffen Neumann]

We have some strange colour problem with pdf graphics,
converted from eps exported by xfig. So there is plenty 
of ways where the problem is rooted :-(

We have two simple graphics, t1.eps and t2.eps.
They differ only in the definition of one color,
as diff shows:

	aipc10(sneumann):t>diff t1.ps t2.ps 
	6126c6126
	< /col1 {0.000 0.000 0.000 srgb} bind def
	---
	> /col1 {0.000 0.000 1.000 srgb} bind def

col1 us used for the words "Applikation":

	grep col1 t1.ps
	...
	1 -1 sc (Applikation) col1 sh gr

The first included image should have black {0.000 0.000 0.000 srgb}
Text, the second blue Text {0.000 0.000 1.000 srgb}.

However, first images uses the TeX-Textcolor red, 
set beforehand using \color{red}.
An example can be seen in

Any Ideas where to continue to look for the problem ?

Yours,
Steffen

There is also a tgz archive with the important files on

Another report is at http://privatewww.essex.ac.uk/~mjreed/tmp/index.html
We use xfig 3.2.3d and gs7 on SuSE Linux, also tried TeXLive7 on Solaris.
