The coloring in your urine is primarily caused by the pigment urochrome.

Urochrome is created when your body processes dead blood cells in your liver, and exits your body mostly through your urinary tract. 

The more water you drink, the more diluted the  urochrome will be, and thus makes lighter colored pee. Keep in mind that there are a *lot* of factors that contribute to the color of your pee; vitamins, minerals, hormones, and diet are just some of the things that can change your urine color.
