If an individual's urine is light, then he is either getting plenty of fluids or taking a diuretic, according to WebMD. There are also certain medications that can turn a person's urine fluorescent green or blue. Consuming carrots has been known to tinge urine orange.
Whenever urine is a rich yellow color, it can be a sign that a person is not getting enough fluids, notes WebMD. Urine can be a dark color because the body is holding onto whatever fluids it can, which is often the case when an individual does not regularly replenish his fluids.
Red urine is usually an indication of the presence of blood, says WebMD. Red urine is not always a reason to be concerned since a single drop of blood can cause an entire toilet bowl to turn red. Blood in urine can also be an indication of cancer or an infection in the body. An infection is more likely if the urine is bloody as well as cloudy.
The way urine smells is just as important as the way it looks, according to WebMD. Strong smells can be a sign of an infection, while sweet smells can be caused by too much sugar in diabetics. Asparagus and other foods have also been known to alter the smell of urine.
