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 sometimes urine can turn colors far beyond what's normal, including red, blue, green, dark brown and cloudy white.

- Visible blood in your urine. Bloody urine is common in urinary tract infections and kidney stones. Both of these problems usually cause pain. Painless bleeding may signal a more serious problem, such as cancer.
- Dark or orange urine. If your urine is dark or orange — particularly if you also have pale stools and yellow skin and eyes — your liver might be malfunctioning.
