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 may change your urine color. Beets, berries and fava beans are among the foods most likely to affect urine color. Many over-the-counter and prescription medications give urine vivid tones, such as raspberry red, lemon 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.
