While peeing in the colors of the rainbow sounds like a great idea (well, it sounds like a great idea to me, anyway), you will notice that a lot of stuff on this list can be dangerous to ingest, even fatal. Therefore, I take no responsibilty if you decide to try any of this.

Also, some of these conditions that cause funny colored pee are symptoms of serious medical conditions. If you see them and are worried, go see your doctor. Now for the list (note: yellow/amber urine is usually the natural color).
