Colorless urine means a person drinks plenty of water and may have to reduce water intake, while pale-straw color indicates a normal, healthy and properly hydrated body, reports Cleveland Clinic. Transparent-yellow and dark-yellow urine colors also indicate a normal body, but the latter hue means a person should drink water soon. Amber urine signals inadequate water intake, whereas syrup urine likely indicates liver disease or serious dehydration and requires a doctor's diagnosis if the color persists.
People who eat rhubarb, blueberries or beets tend to have pink to reddish urine temporarily, notes Cleveland Clinic. However, if they develop this urine color without eating the said foods, then the color possibly signals prostate problems, urinary tract infections, tumors or kidney disease. Mercury or lead poisoning is also a potential cause.
Orange urine means a person consumed food dye, does not drink enough water, or has a liver or bile duct problem, notes Cleveland Clinic. Foaming urine may signal a kidney condition or too much protein consumption.
In some cases, a rare genetic disease causes blue or green urine, a color that also results from urinary tract infections, food dye consumption or medication intake, according to Cleveland Clinic. Medications and drugs that can affect urine color include chemotherapy drugs, laxatives and dyes used by doctors during diagnostic tests. Doctors perform a urinalysis and physical examination to diagnose conditions.
