paint call-outs?

Depends on who the manufacturer is.  Tamiya usually calls for Tamiya paints, Revell kits sometimes call for Testors, ans so on.

And that's IF the manufacturer calls out certain paint companies.  Not all kits do call for a certain paint

Depends on the manufacturer. The numbers you quote certainly sound like they correspond to Humbrol. They should say somewhere on the instructions.
