Urine Color Hydration Check
Use the swatches to read a practical hydration signal, then check the safety notes for colors that may need medical attention.
Quick answer
Pale straw to yellow urine (#1-3 on the scale) usually means you are well hydrated. Dark yellow to amber means drink more. Brown, red, or pink urine can point to issues beyond hydration and deserves medical advice.

How to use the urine color chart
Check your urine color in natural daylight or a well-lit room because toilet water and artificial lighting can shift the shade. Match the closest swatch and tap it for the verdict. First-morning urine is usually darker, so a mid-morning check after your first drink is more useful.
What affects urine color besides hydration
Hydration is a major driver, but it is not the only one. Riboflavin in B-vitamin supplements can make urine bright yellow; medicines such as rifampin or phenazopyridine can turn it orange or red; beets and berries can add a red tint. Liver or bile-duct problems can also make urine brown or tea-colored.
When to see a doctor
Seek medical advice promptly if urine is brown, tea-colored, red, or pink without an obvious food or medicine cause, or if dark urine continues after increasing fluids. Pain, burning, unusual odor, fever, swelling, or blood in urine should not be treated as a hydration problem.
Frequently asked
What does dark yellow urine mean?
Dark yellow urine usually means mild dehydration: your kidneys are conserving water. Drink one or two glasses of water and check whether the color lightens over the next few hours.
What color should urine be?
A pale straw to light yellow color is the everyday target for most healthy adults. Completely clear urine can happen after heavy fluid intake, while amber or darker shades need more attention.
Why is my urine orange or brown?
Orange or brown urine can come from severe dehydration, some medicines, B-vitamins, food dyes, or liver and bile-duct problems. Contact a healthcare provider if it persists or has no clear food or medicine cause.
Does urine color change after coffee or tea?
Coffee and tea can affect fluid balance, but supplements, medicines, beets, and artificial dyes often change color more dramatically. Use this tool only as a general hydration screen.
