Persistant dark or brown urine can indicate liver disease (as long as you are drinking enough water and know it's not dehydration).
Cloudy, murky, or turbid (muddy) urine is characteristic of a urinary tract infection, which may also have an offensive smell.
Murky urine may also be caused by the presence of bacteria, mucus, white blood cells or red blood cells, epithelial cells, fat, or phosphates.
Pink, red, or smoky brown urine can be a side effect of medication or caused by recent consumption of beets, blackberries or certain food colorings. Urinary tract disorder in which bleeding occurs such as cystitis, enlarged prostate, kidney cancer, bladder tumor, tuberculosis, bladder stones, kidney infection, Wilms' tumor (in children), or hypernephroma. Hemolytic anemia and porphyria. It may also occur after trauma to the kidneys or urinary tract.
Dark yellow or orange urine can be caused by recent use of laxatives or consumption of B complex vitamins or carotene. Medications that cause orange urine are pyridium, rifampin, and warfarin.
Green or blue urine is due to the effect of artificial color in food or drug. May be caused by a blue dye such as methylene blue, a component in several medications (Trac Tabs, Urised, Uroblue). Amitriptyline, indomethacin, resorcinol, triamterine, cimetidine, phenergan, and several multivitamins also lend a blue-green tint to the urine. Administration of the dye, indigo carmine, turns the urine blue/green and can last for several days if kidney function is poor. An inherited form of high calcium (called “familial hypercalcemia”) can result in blue urine, which has lent this disease the nickname “blue diaper syndrome." A blue pigment may also be produced by infection with the bacteria Pseudomonas.
