or  par(col = "white"),
as Marc has suggested.

legend()'s source code makes it very straightforward to add an
argument 'text.col' for this purpose, and I have already done so
in my development version.
The question is really if the default should be
   text.col = par("col")
or text.col = par("fg")

I'd currently tend for  par("col") , but the tendency is weak.
