Urine colors (besides yellow) result from medications, food dyes and foods, and various health conditions. For example, pink or red urine can result from urinary blood that infections, cancer, kidney or bladder stones or long-distance running, but eating beets or blackberries can turn urine red too, notes Mayo Clinic.
When urine comes out orange, the cause is usually a medication such as rifampin or phenazopyridine, a laxative or one of a few chemotherapy drugs. Orange urine can also signify an issue with the bile duct or liver, particularly if the stools are also light. Dehydration can deepen the color of urine, making it look orange, according to Mayo Clinic.
Urine that is blue or green can result from some food dyes or testing dyes for bladder and kidney function. Medications such as amitriptyline, propofol and indomethacin can turn urine blue or green, as can familial hypercalcemia, a disorder also known as blue diaper syndrome. Urine that is dark brown can result from some kidney or liver disorders, antimalarial drugs, some antibiotics, and laxatives with senna or cascara. Eating a lot of rhubarb, aloe or fava beans can also turn urine dark brown. If the urine is yellow but cloudy, kidney stones or urinary tract infections can be the cause, as stated by Mayo Clinic.
