[pdftex] problem with color.sty in pdflatex

[Wybo Dekker]

I think there is a bug in color.sty, although I hardly dare say so, 
because I would expect that the problem would have come up much earlier. 

My impression is that when a page ends with a color, it will also start 
with that color. This is illustrated by the following:

\documentclass{article}
\pdfoutput=1
\usepackage[pdftex]{color}
\usepackage[papersize=100mm]{geometry}
\begin{document}
   I'm supposed to be black, because no color was set until now;
   after me, the color is set to red.
\color[rgb]{1,0,0}

   I'm red, but after me the color is set to green,
   followed by a newpage, so this page ends in green.
   As a result, my black brother on top of this page has turned green. 
\color[rgb]{0,1,0}
\newpage
   I'm supposed to be green; after me comes blue,
   followed by a newpage, so this page ends in blue.
   As a result, my color is actually blue. 
\color[rgb]{0,0,1}
\newpage
   I'm blue and after me, the color stays so, happily,
   because if after me the color would become white,
   I would have been invisible. 
%\color[rgb]{1,1,1}
\end{document}

A similar source in ConTeXt has no problems. 
Do I make a mistake in my source?
Or is this really a bug?
