A pigment called urochrome gives urine its yellow color. The shade of yellow varies, depending on fluid intake. Darker yellow urine is more concentrated and indicates more fluids are needed. Orange urine may indicate a problem with the liver or bile duct.

The antibiotic rifampin, sometimes used to treat tuberculosis, and the drug phenazopyridine, used to treat urinary tract infections, can both turn urine orange. Some chemotherapy drugs have the same effect. Kidney stones and urinary tract infections can also make urine appear murky or cloudy.

Eating beets, blackberries and rhubarb can turn urine pink or red, while asparagus can turn it green and eating large amounts of fava beans can turn urine dark brown.

Changes in urine odor can also indicate a medical problem. A pungent ammonia-like odor may indicate an infection or urinary stones. A sweet smell, caused by excess sugar, may be a sign of diabetes. Blood in the urine could be a sign of infection, enlarged prostate, tumors, cysts, kidney or bladder stones. Seek medical attention if urinary bleeding occurs, or if abnormal urine color or odor persists.
