colors in EPS imported by LaTeX

[Zbigniew Koziol]

gnuplot is a nice tool for creating not too complex figures from 
scientific data.

BTW, does anyone know another open source tool that could be used on 
Linux instead of gnuplot?

BTW2, does there exist a not too complex graphics program that would 
allow to create drawings in EPS format? I have in mind drawings that 
could illustrate certain technical details of various processes in 
physics. Like, for instance, a cross section of a mechanical device 
(drawing lines, circles, arrows, etc, adding text description). I do not 
need a CAD type of complexity.

gnuplot can export drawings into encapsulated postscript (EPS) files 
that next could be imported into LaTeX. Figures displayed in gnuplot 
window are usually colorful. However, when they are exported into EPS 
files, the color information is missed. I want to finally have colors in 
PDF created from LaTeX.

I know that there is a way to edit by hand EPS files and add there color 
table. However, I can not find that information by googling.

Anyone willing to advise if the method is not too complex?
