Urine Color Chart — Complete Reference
Urine Colour Chart — Hydration Status, Causes, and When to Act
| Colour Description | Hydration Status | Most Likely Cause | Possible Medical Cause | What to Do |
|---|---|---|---|---|
| Clear — no colour | Over-hydrated | Drinking excessive water | Diabetes insipidus (rare) | Reduce water intake slightly. Excessive dilution can lower electrolytes. |
| Pale straw — very light yellow | Excellently hydrated | Normal healthy output | None | This is the ideal target colour. |
| Yellow — standard | Well hydrated | Normal urochrome pigment concentration | None | Normal. Maintain current fluid intake. |
| Dark yellow or amber | Mildly dehydrated | Insufficient fluid intake | None | Drink one to two glasses of water now. |
| Honey or dark orange-yellow | Moderately dehydrated | Very low fluid intake or concentrated morning urine | Liver condition (if persistent) | Drink water urgently. See doctor if persists without dietary cause. |
| Orange | Severely dehydrated or dietary | Beta-carotene foods, B2 vitamins, rifampicin antibiotic | Liver or bile duct condition | See doctor if not explained by food or medication. |
| Pink or light red | Dietary | Beets, blackberries, rhubarb, red food dye | Haematuria (blood in urine) — kidney stones, UTI, or tumour | See doctor promptly if not explained by food within 24 hours. |
| Brown or cola-coloured | Medical concern | Exercise-induced rhabdomyolysis, severe dehydration | Liver disease, kidney failure | Seek immediate medical attention — especially after intense exercise. |
| Green or blue-green | Medication or infection | Methylene blue medication, asparagus (rare) | Pseudomonas UTI (rare) | Consult doctor if no medication explains it. |
| Cloudy, milky, or foamy | Infection or other | UTI, kidney stones, high-protein diet (foamy) | Proteinuria (kidney disease) — foamy urine indicates protein | See doctor if persistent beyond one or two days. |

Urine Colour Hydration Scale
The simplest real-time hydration check is to observe urine colour — pale yellow is the target and indicates healthy fluid balance throughout the day.
Urine Colour Hydration Scale — 8 Levels
| Level | Colour Description | Hydration Status and Recommended Action |
|---|---|---|
| Level 1 | Clear — no colour | Over-hydrated. Slow down fluid intake slightly. Excessive water dilutes electrolytes. |
| Level 2 | Very pale straw | Excellent hydration. Maintain current intake. |
| Level 3 ★ | Pale yellow | Well hydrated. This is the ideal target colour throughout the day. |
| Level 4 | Yellow | Adequately hydrated. Normal colour for most of the day. |
| Level 5 | Dark yellow | Slightly dehydrated. Drink one to two glasses of water. |
| Level 6 | Amber | Dehydrated. Drink water now and continue drinking steadily. |
| Level 7 | Dark amber or orange | Moderately to severely dehydrated. Drink water immediately and consider electrolyte replacement. |
| Level 8 | Brown or very dark | Severely dehydrated or possible medical cause. See a doctor — especially if this follows intense exercise or is accompanied by pain. |

Foods and Medications That Change Urine Colour
Substances That Affect Urine Colour
| Substance | Colour Effect on Urine | How Long the Effect Lasts |
|---|---|---|
| Beets and beetroot | Pink to red | Up to 24 hours. Only affects approximately 10–14% of people (a genetic trait). |
| Blackberries and berries | Pink to dark pink | Up to 24 hours. |
| Carrots (large amounts) | Orange-yellow | 24–48 hours. |
| Asparagus | Greenish tint and distinctive sulphur odour | 15 minutes to a few hours after eating. |
| B vitamins — especially riboflavin (B2) | Bright neon or fluorescent yellow | While supplement is actively being excreted. |
| Vitamin C (high dose) | Brighter yellow | While being excreted. |
| Rifampicin (antibiotic for TB) | Orange to red-orange | Throughout the entire course of treatment. |
| Nitrofurantoin (UTI antibiotic) | Yellow to brown | Throughout the course of treatment. |
| Phenazopyridine (bladder pain relief — AZO) | Bright vivid orange | Throughout use — this is expected and harmless. |
| Methylene blue (diagnostic tests and supplements) | Blue to blue-green | Up to 24 hours. |
| Iron supplements | Darker yellow or greenish-brown | Throughout supplementation. |
| Senna laxatives | Yellow-brown to orange-brown | After each use. |

Urine Colour in Pregnancy
Pregnancy increases blood volume and kidney filtration rate — understanding normal urine colour changes during pregnancy helps distinguish expected variation from signs that need attention.
- Dark morning urine — more concentrated urine in the morning is common in pregnancy due to increased fluid needs. Drink water immediately upon waking.
- Cloudy urine — some cloudiness can be normal in pregnancy due to changes in vaginal discharge and kidney filtration. However persistent cloudiness with burning or odour may indicate a UTI which requires prompt treatment during pregnancy.
- Pink or red urine — any blood-tinged urine in pregnancy should be reported to an obstetrician promptly. It can indicate a UTI, kidney stones, or in rare cases more serious conditions.
- Foamy urine — persistent foamy or bubbly urine may indicate proteinuria which can be an early sign of pre-eclampsia and should be evaluated by a healthcare provider.
Hydration Checker
Select your urine colour and enter your body weight to get a hydration level assessment and recommended daily water intake.

Frequently Asked Questions
Healthy urine is pale straw to yellow in colour — this indicates good hydration. The ideal target colour is pale yellow as shown at levels 2 to 3 on the hydration scale above.
Dark yellow urine indicates mild dehydration — your body is concentrating the urine because it needs more fluid. Drink one to two glasses of water and the colour should return to pale yellow within a few hours.
Consistently clear urine means you are drinking more water than your body needs. While this is rarely dangerous in the short term it can dilute electrolytes over time — aim for pale yellow rather than completely clear.
Orange urine can result from severe dehydration, high doses of B vitamins or beta-carotene foods, rifampicin antibiotic, or phenazopyridine bladder pain medication. Persistent orange urine not explained by diet or medication should be evaluated by a doctor as it can indicate a liver or bile duct condition.
Pink urine after eating beets or berries is harmless and temporary — only approximately 10–14% of people experience this effect. Pink urine not explained by recent food intake should be evaluated by a doctor as it may indicate blood in the urine.
Occasional bubbles in urine are normal — the result of urine hitting the water in the toilet bowl. Persistently foamy or frothy urine can indicate proteinuria — excess protein in the urine — which may be a sign of kidney disease and warrants a urine test.
Stress itself does not directly change urine colour but stress-related dehydration — forgetting to drink fluids when busy or anxious — will cause the urine to darken. Stress hormones can also reduce kidney filtration rate slightly.
Brown or cola-coloured urine after intense exercise can be a sign of rhabdomyolysis — the breakdown of muscle tissue that releases myoglobin into the bloodstream. This is a medical emergency — stop exercise and seek immediate medical attention.
