*The prismatic pee collection seen in this stunning photo took only a week to assemble for medical laboratory scientists at Tacoma General Hospital in Tacoma, Washington. *
None of the urine samples were treated with chemicals in the lab to change their hue, West said.
Here are some of the reasons for the pee shades:
Red: Blood is the most common cause of red urine, and is a definite health warning signal. More benignly, eating a lot of beets can turn your pee pink.
Orange: Dark-colored urine also points to health problems. Liver cancer can cause dark brown urine, containing excess bilirubin, a brownish pigment produced by the liver. A drug called phenazopyridine (Pyridium) created the bright orange urine seen in West's photograph.
Yellow: Dehydration may cause a dark yellow colored urine. Without enough water, a pigment called urochrome becomes more concentrated in urine. On the other hand, in hospitals, some patients on intravenous fluids are so hydrated they produce nearly colorless urine, West said. The cloudy, yellow urine in West's picture was caused by an infection.
Green: Green urine usually flows from dilution of blue urine, as in West's image. Occasionally, a urinary tract infection may trigger green pee.
Blue: The rarest of all on the pee rainbow, blue urine often comes from chemicals and drugs given to patients. The No. 1 offender is a drug called methylene blue, used to treat carbon monoxide poisoning, and as a dye during surgery. It makes the blue and green urine seen in West's photograph. Genetic conditions that affect the breakdown of dietary nutrients can also cause blue urine. Even blue food dyes sometimes passes into pee.
Indigo and Violet: In this photo, the deep purple urine comes from a patient with kidney failure. Patients with catheters can develop a rare complication called "purple urine bag syndrome," linked to a urinary tract infection and highly alkaline urine. A genetic condition called porphyria may also trigger deep purple pee.
