Color temperature refers to the color spectrum that a black body would emit if heated to a certain temperature on the Kelvin scale. Cooler temps are redder, like embers in a fire. Hotter temps go to white, then blue. Think about a candle flame. The hotter center part is blue, then yellow in the outer, cooler portions.
Your tungsten film is balanced for somewhere in the 2750K to 3200K range, and daylight is hotter, at about 5000K or so. Putting the "hotter" daylight onto the film will make it and the objects reflecting it appear excessively blue.
