In all honesty, depends what instrument is used to measure the SG in the
first place. And what RGB color space is used to convert the measured Lab
numbers to. Haven't you received a Lab text file with your SG in the form of
a CD? If you care to send me that file, I'll see if I can convert it to your
choice of RGB.
