Of main importance for the expected behavior of color centers seems to be [[ligand field theory]]. 
Basic classification into high spin complex & low spin complex cases. 

Main cases include …
* substitutional atoms
* vacancies
* interstitials
* combinations of the above
Imaginable are further exotic cases like e.g. 0D point defects on some type of 1D dislocations or 2D stacking order faults? 
Just for one random idea.

For substitutionals atoms the mismatch of atom size can be a factor in energies involved and this frequencies. 
Transition metals in silicon being same period similar size and thus rather low energy inclusions => low IR frequencies.
