Re: v9: variable name colour?
For Mathematica 9 on Mac OS X, it's still the case that a user-defined name to which no value has been assigned is blue; once a value is assigned (and the cell where it's assigned is evaluated), the name turns to black.

Am I missing something simple? Apologies if I am. --- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
