Are you talking about shooting digitally? If so, I wouldn't shoot at 3200K on your camera and then try to color-correct it back to neutral just for a cooler cast - unless you are shooting raw with a camera that doesn't bake-in color temperature, in which case it doesn't really matter anyway what you set. But if you are shooting in an RGB format like ProRes, etc. then don't record a very blue image and then try to make it neutral again. This isn't like shooting on color negative film where there is color information in all three layers, just imbalanced by shooting on tungsten stock in daylight with no correction. If you are recording RGB, it's more like what you see is what you get -- if the image is very blue, then it's missing a lot of red. And it's even worse if it's a display gamma recording rather than log.
If you want a colder look, then shoot in daylight at a color temperature setting lower than 5600K, like 4300K or 4700K. That should give you a colder cast.
With digital color-correction, it is easier to do things like reduce saturation in the red channel, or shift your shadows and blacks towards the blue relative to the highlights, etc. There is no reason to record radically incorrect color casts. This isn't like printing a film negative where you are trying to trick the print stock to behave in a certain way because you have no digital color-correction tools.
