I believe you will find that photos taken later in the day are very blue, something like 5,000 or 6,000 Kelvin or higher. Whereas Tungsten assumes a white balance in the area of 3,200* Kelvin, more or less.
If you have a digital camera to test with, set the White Balance to "Daylight" (not "Auto") and take a series of photos. Put it on a tripod, select a medium aperture such as f/4 or f/5.6 and let the camera set the shutter speed. Later, compare the results.
