if you shoot RAW there is nothing to control in camera, you merely get a starting point when you open it in a raw editor.
Ahem, that's incorrect. Your RAW editor will have one heck of a time fixing colour casts resulting from mixing light sources with different hues. There are quite a number of variables to control in camera, at the moment the exposure is taken.
@OP, it'd be great if you could post an example of a 'problem photo'. In general, you will er, generally, get some casts from the light bouncing off surfaces. This is NORMAL. I'd call these natural colour casts, viz. the slightly greenish tint you get from sunlight bouncing off grass, and wouldn't sweat them too much. You could 'neutralise' them in post processing, but that would also yield a photo that is too neutral as to be irrealistic—say, spot on skin, but magenta-ish grass—not good.
If you're working with more than just natural light (i.e. flash), then you need to be more careful and consider gelling the flash to match the other colours in the scene. Again, without an specific example, it's hard to guide you.
