Well, kinda.

When I fiddle with my plasma sphere, I get two colors out of it.  The main
bolts are bluish.  The surface of the inner electrode and the inside of the 
sphere where your hand makes contact is pink.

I believe that there two gasses with different breakdown voltages.  Different
gasses glow in different areas due to differing charge densities at the
electrodes and in space.

Does anyone have a better theory?
