Hello,
        Not having 5.1 yet, I don't know exactly what the problem is but one
good reason might be that some of the colours in Graphics`Colors` have names
that clash with other useful packages.  Because of this, I have long had a
private version which loads with the following message:

Graphics`Colors` - loading modified version of this standard package in
which \
the colors
{Cobalt, Gold, Gray, Titanium, Zinc}
have been renamed:
{CobaltColor, GoldColor, GrayColor, TitaniumColor, ZincColor}
to eliminate clashes with the standard packages
Miscellaneous`ChemicalElements` and Miscellaneous`Units`.

I'm not sure if this explains a problem with Black though.
