In order to maintain a proper white balance, first you'll need references--like a grey card or a white card. These allow you to calibrate the white balance in-camera or in post with decent results.


However, if you're using a 3200K bulb, it will be difficult to balance the light with other ambient light (assuming they, too, aren't 3200K bulbs). Once you shift the white balance, you're shifting it for all available light sources (no matter their color). Therefore, all your light sources need to be the same color before you shift (you can gel your light sources to balance them with ambient).
