Healthy urine varies in color from pale yellow to deep amber, according to WebMD. Urochrome, a pigment found in urine, determines its color, with heavier concentrations causing darker colors. Dark urine generally signifies insufficient fluid intake.
Very pale urine often indicates excess fluid intake or the use of diuretics, which are drugs that cause the body to rid itself of excess fluid, advises WebMD. Vitamins can make the urine yellow, while eating carrots may turn the urine orange. Red urine indicates blood in the urine and may indicate a serious underlying medical condition, while cloudy urine tinged with blood often indicates a urinary infection, both of which require evaluation by a medical professional.
