Forcing Black on RTF Text generated from NSAttributedString

The default text color for an NSAttributedString is black.  If I
extract RTF from a plain, black, string the resulting RTF doesn't have
black in it's table, and it doesn't include a color directive that
leads me to believe it should be marked as black.

When I take that RTF data to a PC running our application what I get
out is a gray looking text (for some reason).

I'd like to force the text in my string which doesn't have a color
associated with it, to use black.  I wrote some code that runs through
the string and for every text range that doesn't have a color
associated with it, it tries to set the color for that range to black.

Unfortunately (or not) the addAttribute: routine is clever enough to
figure out that I'm trying to add black as a color so it refuses to
actually add the color to the text range.  If I check the string after
my addition, the attribute for that range of text is still NULL.  :-(

Is there any way to tell the attributed string "No really, I want to
store black, explicitly, as the foreground color of this range of
text.... I really, really do!"
