Indeed, Jae-Joon is correct.  I now see why Nicolas's code did not work.
The assignment of _AXINFO occurred after the initial creation of the axes
panels.  While the code does reuse the _AXINFO data for some things in later
redraws, it does not re-use the color information.  I should also point out
that changing the _AXINFO data has the side affect of being applicable to
all future instantiations of 3D axes within that process run.  That could be
a bug or a feature, but it is something to be aware of in the future.
