Color Temp Of Lights

It is my contention that color temperature plays no role in "optimal" lighting; it's the construction of the reflector and the angularity of the light which counts. Halogens are known for revealing details, but that's because they tend to be focused and aimed by reflectors rather than diffused like a Soft White. If you put a 4000k pin-source light in front of a halogen reflector, it'd do the same thing.

That's the point of "White Balance."

Any light can be corrected for. Some cameras do it better than others, and I always advise doing it in-camera if at all possible. Post-processing software is another learning curve of its' own, and serves to complicate the process. If you can avoid it by getting the color right in the camera, it makes sense to do so.
