Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is.
Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color. Many over-the-counter and prescription medications give urine vivid tones, such as red, yellow or greenish blue.
An unusual urine color can be a sign of disease. For instance, deep red to brown urine is an identifying characteristic of porphyria, a rare, inherited disorder of red blood cells.
Normal urine color varies, depending on how much water you drink. Fluids dilute the yellow pigments in urine, so the more you drink, the clearer your urine looks. When you drink less, the color becomes more concentrated. Severe dehydration can produce urine the color of amber.
But urine can turn colors far beyond what’s normal, including red, blue, green, dark brown and cloudy white.

Your urinary system — which includes the kidneys, ureters, bladder and urethra — is responsible for removing waste from your body through urine. Your kidneys, located toward the back in your upper abdomen, produce urine by filtering waste and fluid from your blood. That urine then travels through your ureters to your bladder, where the urine is stored until you can eliminate it at an appropriate time.
