No, they could give you the coordinates in CIE L*a*b, either that or you
take a photospectrometer to a swatch they sent you, which would cost
roughly the same as the monitor with built-in calibration.

Really, any time you have a photo (or really, anything else) printed
(even, say someone's portrait) you want to use calibrated color. Here's
the deal: When adjusting the color balance and tone density of a photo,
you want to be sure that 1) the picture will appear on paper without
losing any detail in shadows or highlights, 2) [Most critical to have a
calibrated monitor for] the color balance is correct. If you're
adjusting color on an LCD monitor and that monitor has a green cast,
your perception will shift, once you have the picture balanced the way
you think it should be, and you send it to a press or lab for printing,
or e-mail the image to a friend, you'll soon discover that on all of the
other media, even though the picture looks fine on your screen, the
shadows are blocked up, the midtones are too dark, and everything looks
like it was tinted with a bit of pepto-bismol (everything's magenta).
That is why you want a calibrated screen.
