Oops, I noted in my previous message that Munsell has beta software to
convert other vendor color notations to Munsell color notations.  This
is incorrect.  The beta software converts Munsell color notations to
XYZ, Lab, RGB, and CMYK color notations.
 
Also note that the colors depicted onscreen do not match Munsell color
chips.  Onscreen colors are an approximation only, and vary with
individual screens.
 
Sorry for the misinformation.  LAR
