No.

Yes.

The high voltage supply of the monochrome monitor doesn't generate
a high enough second anode voltage for the color tube.  And you can't
use the HV supply from the Mac Color Classic because it depends on
a higher vertical scan rate than the IIc produces.

It's one of those things that's theoretically possible if you do enough
work and buy enough parts, but it will take a *lot* of time and cost
more than buying yourself a suitable color monitor.
