Red, green, yellow, blue—urine comes in a variety of shades and hues, but peeing different colors of the rainbow is not always healthy. That’s why it is good to know what your urine says about your health.
Sometimes red pee indicates kidney disease or urinary tract infections, but it’s also possible that you recently ate food with a certain pigment. For example, eating beets can result in beeturia—the passing of red or pink urine because of a compound called betanin in the vegetable.
Since pee is such a useful tool of diagnosis, the Cleveland Clinic—a non-profit academic medical center in Ohio—made an infographic about the hue of your liquid excreta. Of course, if you are worried about the color of your urine, the Cleveland Clinic recommends you visit your doctor.
Note: While the infographic says there is no such thing as purple pee, Mayo Clinic disagrees: "Deep purple urine is an identifying characteristic of porphyria, a rare, inherited disorder of red blood cells.”
