Let:
\documentclass{article}\usepackage{color}
\begin{document}  \color{blue} Hello
\end{document}
As I can see "Hello" in blue on my screen, does this prove that TeX
can deal with color ? It depends on the point of view, I presume.
In the doc of MSWord, it is stated that equations are embedded via
OLE links. If you know from some other source that this is not true,
then OK, I believe you. Anyway, it's not important for the future of
LaTeX.
