please note, that VMD generated .pdb file contain no bond information.
the bond information is generated heuristically upon reading the
coordinates. if you'd also save a .psf file, VMD would recognize
the bonding information stored there. note, that this .psf file
cannot be used for simulations only for visualization, as it only
contains a subset of the information needed (e.g. no angles/dihedrals).

PG> color type nothing changes from color by name. How to fix this problem?

please explain what you'd expect. most likely this is again due to
lost information by writing the .pdb file.

cheers,
