Urine color generally ranges from a pale-yellow color to deep amber. This coloring is primarily caused by the pigment urochrome. Whether your urine is diluted by water or more concentrated determines how the pigment will appear. The more water you drink, and the more hydrated you become, the lighter the pigment in your urine. The pigments and chemical compounds in the foods you eat and the medications you take can also alter the color of your urine. These changes are fairly standard and typically don’t last for long. Certain changes in color may be a sign of an underlying medical condition.
