Just take a Kodak gray card to a Sherwin Williams store. They can scan it 
with a spectrophotometer and match it exactly.

Does anyone know if Kodak gray cards really have a flat spectral response?
It seems to me that they were originally designed for taking light meter
readings from, not for setting the white balance in a digital camera. Has
anyone taken a full spectro reading from one in sunlight, say with an
Eye-One Pro? I have an Eye-One, but don't have a Kodak gray card.

Take a look here, Paul: The Kodak card seems to have a flattish (but not the
flattest) spectral response.

They are only average and not calibrated, good enough to take meter readings 
from and maybe to get a rough colour balace if you included one in a shot, but not 
by any means made to a particular tight specification. Macbeth Colour checkers 
are for that and that is why they are so expensive.
