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
If everything is normal and healthy, the color should be a pale yellow to gold. That hue comes from a pigment your body makes called urochrome. 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 urine can turn colors far beyond what's normal, including red, blue, green, dark brown and cloudy white.
Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color. Urine color can also be a symptom of illness https://www.mayoclinic.org/diseases-conditions/urine-color/symptoms-causes/syc-20367333
Despite its alarming appearance, red urine isn't necessarily serious. Red or pink urine can be caused by:
Blood. Factors that can cause urinary blood (hematuria) include urinary tract infections, an enlarged prostate, cancerous and noncancerous tumors, kidney cysts, long-distance running, and kidney or bladder stones.
Foods. Beets, blackberries and rhubarb can turn urine red or pink.
Medications. Rifampin (Rifadin, Rimactane), an antibiotic often used to treat tuberculosis, can turn urine reddish orange — as can phenazopyridine (Pyridium), a drug that numbs urinary tract discomfort, and laxatives containing senna.
