Ok, didn't know that. I thought color.tex is for color support in plain TeX.

To give some background:

I am completely reworking the PSTricks driver for gnuplot to support all 
features and give full color support using 'xcolor'. But this would be 
usable only with LaTeX.
To retain basic color support also for use with TeX I was hoping that I 
could use the same makros \textcolor and \color in plain TeX.

I have to see how I can manage this.
