We ’re accustomed to learn urine as yellow , or , if we ’re extremely hydrous , absolved . That does n’t mean that pee ca n’t have all sort of color . have ’s explore the biochemistry of making one ’s pee all the colors of the rainbow .
Red
Well , this is an gentle one . It might be blood reddening your pee , in which case get to a hospital and remain there until they figure out how to treat you . It could be vesica cancer , or it might be something as relatively benign as kidney Stone . On the other hand , it might be beets making your pee ruby , in which case , keep consume ! They ’re low - calorie , gamy - fibre , and filled with vitamins . They ’re also fill with betanin — proof that not all food for thought additives are bad . Betanin is harvest from beet and put into a few food as cerise coloring . It only goes in frozen foods or foods mean to be eaten presently , as sunlight and oxygen disgrace it . Betanin is a delicate dye , but a tidy sum of mass lack the enzyme that will break it down in their stomach . Those people have red or pinkish pee .
Orange
Again , this can be a problem . Bilirubin is a yellow - orange tree , and it ’s usually in urine . It ’s the product of the rude breakdown of the heme in Hb . Too much , though , can suggest liver cancer . Alternately , you could have just taken some Pyridium . This is a drug given to people who have had procedure done on their urinary nerve pathway , or have some urinary piece of ground irritation . When it make its way through the body , it breaks down into components that pop pain in the mucosal lining of the urinary tract . Those components also turn your water to orange sport drunkenness , but this is harmless .
white-livered
This one you could work out out on your own .
Green
Pseudomonas aeruginosa is most common in healthcare configurations , in part because it travel around hospitals , and in part because it ’s most present in people with compromised resistant organisation . This bacteria usually go down in the urinary tract , and makes everything that comes out of that parcel , pus and pee , bend a bit green . Unless you ’re seriously dedicated to a pee rainbow , keep off this .
downcast
The best way to get blue piss is with drab dyestuff . The soundbox does n’t let out down a lot of blue dye , so even eat up something racy can cause you to pee grim . I do it one person who went to a Star Wars - theme Browning automatic rifle and toast “ blue milk . ” They were warned by their waitress that they ’d be micturate drear , but there ’s nothing like a lot of gloomy milk to make you forget your waitress ’ warning .
There ’s also methylene group blue . This heart was used to treat malaria about a century ago , and as resistivity to drug increases , and money available to treat malaria patients lessen , it might become the standard once again . The drawback is it induce both pee and the tweed of one ’s eyes to turn blue . This only happens when the taker is fairly dehydrated . When dilute , methylene group blue turns the urine a gracious light immature color that does n’t need a urinary piece of land infection .
reddish blue
Phenolphthalein has a venerable history as a laxative , and an every bit venerable history of turn people ’s urine into a purple - violent colouring , but only if the weewee is very more or less basic . The regretful news is bacteria often deform water alkaline . The good tidings is a vegetarian diet of fruit , legume , and vegetables can also work pee alkaline . So mayhap you ’re not infected , you ’re just vegetarian . ( Though how you deal to be vegetarian and constipated is anyone ’s speculation . )
black-market
Just as a bonus , several different antibiotics , let in metronidazole and alpha methyl dopa seem to turn urine black . But not to worry ! These chemicals just bend black on contact with bleaching agent , which is a pop choice for scavenge toilet bowl . So the urine will only turn black-market outside the body .
