If the white balance doesn't work the culprit may be your daylight bulbs.
There are several types of daylight bulbs and they have varying temperatures. You know how if you take a picture next to a regular lamp it's too yellow? The opposite happens with the daylight bulbs and its too blue.
An ideal bulb temp is between 5,000-7,000. Even then you may get some blue hues but after that it really gives a blue tint.
It should say the temp on the box of the light bulb.
