[Xy-pic] color in xymatrix diagram spreads throughout document

Hello,
I am trying to color arrows in a diagram that I construct with Xy-pic
v3.82 and pdflatex v1.40.4. I find that coloring curved arrows also
colors every subsequent object in my diagram -- and most subsequent
parts of my document to boot. I've looked for solutions in the Xy-pic
documentation, but I haven't found any. Can someone point me to what
I'm doing wrong?
Here is a minimal example:
\documentclass{article}
\usepackage{color}
\usepackage[all]{xy}
\begin{document}
\xymatrix{
X \ar@[red][r] & M\\
X \ar@[red]@/^/[r] & M\\
X \ar[r] & M
}
\end{document}
I want nothing to be red except the arrows in the first two lines of
the diagram. The first line renders as expected: only the arrow is
red. In the second line, the arrow is curved and red as expected, but
M is also red. And in the third line, everything is red.
Thank you,
John
