This could be problematic... if you go to work on a system you don't know what
the wire colors mean until you determine if the system is grounded or not. I
think this stems from AC wiring standards and colors being applied to DC
systems. IMO someone needs to think this through and come up with a color code
for DC that is the same regardless of the grounding or system voltage.
