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.
I agree, I would expect the lines around the legend's box in par("fg"), but the font in par("col"). And indeed, that's already the case if both values have been set in par().

Martin,
Thanks for taking this on.
I'll throw in my vote and support the text.col = par("col") approach.
There is little consistency to the interpretation of these parameters across different functions, but my preference would be to use "col"
