What color is your urine? Urine can change color throughout the day, and many changes are completely harmless. The amount of fluid you drink, certain foods, vitamins and medications can all affect how your urine looks.
But sometimes an unusual urine color can provide a clue that something needs medical attention. Pink or red urine, for example, can indicate blood, while orange or dark-brown urine may sometimes be associated with liver, bile duct, kidney or other health problems.
So, what does your urine color actually mean?

Quick Answer
Healthy urine is usually clear to pale yellow or light straw-colored. Darker yellow urine commonly occurs when urine is more concentrated, such as with dehydration. Foods, food dyes, vitamins and medications can also temporarily change urine color.
Some colors deserve more attention. Pink or red urine may indicate blood, orange urine can sometimes be linked to dehydration or liver and bile duct problems, and dark-brown or cola-colored urine may have several possible causes. Blue or green urine is uncommon and may result from dyes, medications or, less commonly, certain infections.
Urine color alone cannot diagnose a medical condition. If an unusual color persists, keeps returning, or occurs with pain, fever, burning while urinating, jaundice or visible blood, talk with a healthcare professional.
What Color Is Your Urine? What Is Normal?
Normal urine generally ranges from clear to pale yellow or light straw-colored. The exact shade varies depending largely on how concentrated the urine is.
When you drink more fluids, urine becomes more diluted and tends to look lighter. When you drink less, the urine becomes more concentrated and may appear darker yellow or amber.
Urine gets its yellow color from pigments produced as the body processes substances such as bilirubin-related compounds.
However, hydration isn’t the only factor. Foods, food coloring, vitamins and medications can also change the appearance of urine.
7 Urine Colors and What They May Mean
Can Kidney Stones Cause a Kidney Infection?
1. Clear or Transparent Urine
What it may mean: High fluid intake or very diluted urine.
Completely clear urine occasionally is usually not concerning, particularly if you have recently consumed a lot of fluids.
However, consistently clear urine despite not drinking unusually large amounts may be worth discussing with a healthcare professional, especially if you also have excessive thirst or frequent urination.
The goal isn’t necessarily to make your urine completely clear. Pale yellow urine is generally a more typical appearance.
2. Pale Yellow or Light Straw Urine
What it may mean: Normal hydration.
Pale yellow or light straw-colored urine is generally considered a typical healthy appearance.
Your urine may become lighter after drinking fluids and slightly darker later in the day. Small day-to-day variations are normal.
Is pale yellow urine healthy?
Usually, yes. Pale yellow urine commonly indicates that your urine is not highly concentrated.
But remember that urine color is only one health clue. Normal-looking urine does not rule out kidney disease or other medical conditions.

3. Dark Yellow or Amber Urine
What it may mean: Dehydration or concentrated urine.
Dark yellow urine is commonly associated with dehydration. When your body has less available water, urine becomes more concentrated and its yellow color becomes stronger.
This can happen after:
- Sweating heavily
- Exercising
- Spending time in hot weather
- Not drinking enough fluids
- Vomiting or diarrhea
- Going several hours without drinking
If dehydration is the likely cause, drinking an appropriate amount of fluids should gradually make your urine lighter.
If dark urine continues despite adequate hydration, or if you develop other symptoms, speak with a healthcare professional.

4. Orange Urine
What it may mean: Dehydration, foods, vitamins, medications or, sometimes, a liver or bile duct problem.
Orange urine can have several explanations.
Dehydration can make urine appear orange because the urine becomes more concentrated. Certain vitamins, foods and medications can also change urine to an orange or yellow-orange color.
One important reason to pay attention to persistent orange urine is that it can sometimes be associated with liver or bile duct problems.
When is orange urine more concerning?
Contact a healthcare professional if orange urine persists, particularly if it occurs together with:
- Yellow skin or eyes
- Pale or clay-colored stools
- Abdominal discomfort
- Significant fatigue
- Other unexplained symptoms
Mayo Clinic notes that orange urine accompanied by pale stools or jaundice can be a sign of a liver or bile duct problem.

5. Pink or Red Urine
What it may mean: Food pigments, medications or blood in the urine.
Pink or red urine can sometimes result from foods such as beets, blackberries or rhubarb. Certain medications can also change urine to a reddish or orange-red color.
But red or pink urine can also mean blood is present in the urine.
Possible causes of blood in urine include:
- Urinary tract infections
- Kidney stones
- Kidney or bladder problems
- Prostate-related conditions
- Vigorous exercise
- Other urinary tract conditions
In some cases, blood in the urine can be associated with more serious conditions, including certain cancers.
Should you worry about red urine?
Don’t automatically assume the worst, because food and medications can cause harmless color changes.
However, visible blood in urine should be medically evaluated, particularly when you cannot clearly explain the color change.
Seek medical advice if your urine is red, pink or visibly bloody and the cause isn’t obvious.

6. Blue or Green Urine
What it may mean: Food dyes, medications, medical dyes or, less commonly, certain infections.
Blue or green urine is uncommon.
Possible causes include:
- Food coloring
- Certain medications
- Dyes used during some medical tests
- Certain urinary tract infections
Some medications can produce greenish-blue urine, while particular bacteria associated with urinary tract infections can sometimes cause green urine.
If the color appears once after eating strongly colored foods or taking a medication known to affect urine color, it may be temporary.
If blue or green urine persists without an obvious explanation, talk with a healthcare professional.
7. Dark Brown or Cola-Colored Urine
What it may mean: Severe dehydration, certain foods or medications, liver or kidney problems, bleeding, or muscle injury after extreme exercise.
Dark brown or cola-colored urine deserves more attention than ordinary dark-yellow urine because it has a wider range of possible causes.
Possible explanations include:
- Significant dehydration
- Certain foods
- Certain medications
- Liver disorders
- Kidney disorders
- Some urinary tract conditions
- Blood or blood breakdown products
- Severe muscle injury after extreme exercise
Mayo Clinic notes that extreme exercise can cause muscle injury that produces tea- or cola-colored urine and can potentially damage the kidneys.
Persistent brown urine should be evaluated rather than assumed to be dehydration.

Urine Color Chart
What color is your urine? The answer can provide a useful clue about hydration and other factors, but urine color alone cannot diagnose a medical condition.
| Urine color | Possible explanation | When to pay attention |
|---|---|---|
| Clear | High fluid intake or very diluted urine | Persistent without high fluid intake |
| Pale yellow | Typical hydration | Usually normal |
| Dark yellow/amber | Concentrated urine, often dehydration | Persists despite adequate fluids |
| Orange | Dehydration, foods, vitamins, medications | Especially with jaundice or pale stools |
| Pink/red | Food, medication or blood | Unexplained or persistent |
| Blue/green | Dyes, medications or uncommon infections | Persists without an obvious cause |
| Dark brown/cola | Dehydration, medications, liver/kidney issues or muscle injury | Should be medically assessed if persistent |
What Can Change Your Urine Color?
Urine color isn’t determined by hydration alone.
1. How Much Water You Drink
More fluid generally dilutes urine and makes it lighter. Less fluid concentrates urine and can make it darker.
2. Foods
Some foods can temporarily change urine color.
Examples include:
- Beets
- Blackberries
- Rhubarb
- Fava beans
- Carrots
- Foods containing strong artificial coloring
3. Vitamins
Some vitamin supplements can affect urine appearance.
B-complex vitamins, for example, can make urine appear particularly bright yellow, while certain vitamins may contribute to orange or yellow-orange urine.
4. Medications
Some medicines can cause striking changes in urine color.
For example, phenazopyridine can turn urine orange, while several other medications can produce orange, blue, greenish-blue or brown urine.
If your urine changes after starting a medication, check the medication information or ask your healthcare professional before stopping it.
What About Cloudy or Foamy Urine?
Cloudy urine isn’t really a color, but it is another common change people notice.
Cloudy or murky urine can occur with dehydration, urinary tract infections or kidney stones. However, cloudy urine alone does not necessarily mean that you have an infection.
Persistent foamy or bubbly urine can sometimes indicate protein in the urine. Protein in urine can be an early sign of kidney disease and may require a urine test for proper evaluation.
When Should You See a Doctor About Urine Color?
Consider medical evaluation if:
- Your urine is visibly red or contains blood
- Dark-brown urine persists
- Orange urine continues without an obvious cause
- An unusual color lasts for several days
- You have burning or pain while urinating
- You have fever or chills
- You have significant abdominal, pelvic or back pain
- You notice yellowing of your skin or eyes
- You have persistent cloudy or foamy urine
- Your urine changes and you recently started a medication but aren’t sure whether it can cause the change
Mayo Clinic recommends medical evaluation for blood in the urine and for dark or orange urine, particularly when other symptoms suggest a possible liver or bile duct problem.
What Tests Can Check Abnormal Urine?
If a healthcare professional is concerned about a urine color change, they may recommend a urinalysis.
A urinalysis can examine the urine visually and chemically and can also identify microscopic findings. Depending on the symptoms, additional urine or blood tests may be recommended.
Testing may help identify issues such as:
- Blood in urine
- Protein
- Signs of infection
- Abnormal concentration
- Kidney-related abnormalities
- Other substances that may explain changes in urine
The appropriate tests depend on your symptoms and medical history.
Does Urine Color Show Kidney Health?
Urine color can provide clues, but it cannot reliably tell you whether your kidneys are healthy.
Kidney disease can sometimes develop without obvious changes in urine appearance. The National Kidney Foundation notes that kidney damage can be present even when urine looks normal, which is why appropriate testing matters when kidney disease is suspected.
If you have risk factors for kidney disease, such as diabetes, high blood pressure or a history of kidney problems, discuss appropriate kidney screening with your healthcare professional.
How to Keep Your Urine Healthy
There is no need to constantly monitor the exact shade of your urine.
Instead:
- Drink fluids regularly according to your individual needs.
- Pay attention to persistent changes rather than one unusual bathroom visit.
- Don’t ignore visible blood in your urine.
- Take medications only as prescribed.
- Tell your healthcare professional about persistent changes in urine color or appearance.
- If you have a medical condition that affects fluid intake, follow your clinician’s specific fluid recommendations.

What is the healthiest urine color?
Pale yellow or light straw-colored urine is generally considered a typical healthy urine color. Urine can naturally vary throughout the day depending on fluid intake.
What does dark yellow urine mean?
Dark yellow urine often means the urine is more concentrated, which commonly happens when you haven’t consumed enough fluids or have lost fluids through sweating, vomiting or diarrhea.
What does clear urine mean?
Clear urine often means your urine is highly diluted, which can happen when you drink a large amount of fluid. Occasional clear urine is usually not concerning.
Why is my urine orange?
Orange urine can be caused by dehydration, foods, vitamins or medications. Persistent orange urine, especially with yellow skin or eyes or pale stools, should be evaluated by a healthcare professional.
Why is my urine red?
Red urine can result from foods such as beets or certain medications, but it may also indicate blood in the urine. Unexplained red or pink urine should be medically evaluated.
Is brown urine serious?
Brown urine has several possible causes, ranging from dehydration and certain medications to liver or kidney problems. Cola-colored urine after extreme exercise can also be associated with muscle injury. Persistent brown urine warrants medical evaluation.
Can dehydration change urine color?
Yes. Dehydration makes urine more concentrated, commonly causing it to become darker yellow or amber.
Can vitamins change urine color?
Yes. Certain vitamins, particularly B vitamins, can make urine noticeably brighter yellow, while some vitamins can contribute to orange or yellow-orange urine.
Does red urine always mean blood?
No. Foods and medications can sometimes make urine appear pink or red. However, because blood in the urine can have important causes, unexplained red or pink urine should be checked by a healthcare professional.
Can urine color diagnose kidney disease?
No. Urine color can provide clues but cannot diagnose kidney disease. Kidney problems may exist even when urine looks normal, so medical testing is needed when kidney disease is suspected.
When should I worry about my urine color?
Seek medical advice for unexplained red or bloody urine, persistent dark-brown urine, ongoing orange urine, or urine changes accompanied by pain, fever, burning during urination, jaundice or other concerning symptoms.
