Urine color offers a rough clue, but thirst is a better guide for most people deciding when to drink water. That’s the main takeaway from Yahoo’s report featuring kidney experts. Suzanne Watnick, a kidney specialist at the University of Washington, explains that color charts lack precision. Experts don’t rely on them to manage kidney disease. For our Dark Urine community, that makes shade a clue—not a firm measure of water needs. The report covers expert guidance, not a study testing a drinking routine. It also notes an exception: people prone to kidney stones. Watnick says very pale urine can help guide people who need to stay highly hydrated. That differs from using a color chart as an everyday target for everyone. Food and supplements can change the picture, too. B vitamins, including riboflavin, can turn urine bright yellow. Rhubarb can make it reddish-brown, while beets can turn it pink. Color alone cannot explain the cause of a change. Nor can usual-looking urine rule out kidney disease. The article reports that 37 million US adults have long-term kidney disease. Only one in 10 knows they have it. Those figures concern kidney disease awareness, not how accurately urine color measures water needs. For members tracking Hydration, the useful takeaway is context. A log could pair daily drink amounts with thirst, shade, and recent foods or supplements. Comparing those notes with community peers may reveal patterns worth recording. It does not turn a shade match into a diagnosis or a precise water target. What patterns have you noticed between your urine color, thirst, drink amounts, and supplement routine?
