I've been spending some time experimenting with white balance over the last month. I've been trying to use it creatively and not using it on auto to see the different effects. These are some photos I took on a Red Riding Hood shoot showing how the pictures came out. The first uses tungsten (shade on my camera). The second uses direct sun and the third cloudy. The fourth uses the selective colour mode on my Nikon D5100 with just the red showing. This is a really fun in camera effect and it works particularly well when used with anything red as it's so vibrant and bright.
