White balancing is the process of correcting the colors that your camera picks up prior to shooting to an objective standard, in this case matching the color of white on your camera screen to an objective “true white.” This is necessary so the color of your image is as true to reality as possible, as many digital cameras might pick up hints of other colors, such as red, blue, or even yellow and green, if not white balanced prior to shooting. Most digital cameras come with an automatic white balance built into them, but you’ll still need to point your lens at a white object of some kind to match to.
If you want to get creative, you can manipulate the white balance on purpose in order to get different colors in the shot. Here's a series of shots taken a few seconds apart with different white balance settings along with a neutral shot and an HDR shot with different exposures (the two last shots):
