Hi,
  I think you're going to want to compute the RMSD in a residue-by-residue
manner, assigning the resulting RMSD values to one of the per-atom fields,
such as beta, and then coloring by the field you stored the RMSD into.
I believe there's a simple residue-by-residue RMSD example script included
in the NAMD tutorial that can be made to do what you want:

Cheers,
