The first few images here all show a terrible white balance. The colors are off and the lighting makes them all shaded yellow.

Here the white balance is back to a correct level, followed by several that aren't tuned properly.

As you can see in this image the White Balance is a bit off. Everything has a tint of red/pink to it.

This photo is the opposite. I was a bit to cool with the white balance and because of it ended up with a blueish tint to my photo.

In this photo and the one below you can see the stark contrast in the color of the table cloth. In one it's a bit yellow(up above) and in the picture below it's a bit bluer.
