It is further processed to become the chemical that gives feces its brown color. [1] Bilirubin is a pigment that results from the breakdown of the heme portion of hemoglobin. The liver conjugates bilirubin, making it water-soluble; and the conjugated form is then excreted in urine as urobilinogen and in the feces as stercobilinogen.
Stool that is pale or grey may be caused by insufficient bile output due to conditions such as cholecystitis, gallstones, giardia parasitic infection, hepatitis, chronic pancreatitis, or cirrhosis. Bile pigments from the liver give stool its brownish color. If there is decreased bile output, stool is much lighter in color.
Urobilin is excreted by the kidneys to give urine its yellow color and stercobilin is excreted in the feces giving stool its characteristic brown color. A trace (~1%) of the urobilinogen is reabsorbed into the enterohepatic circulation to be re-excreted in the bile. [41] Conjugated bilirubin's half-life is shorter than delta bilirubin. [42]
Bile has an important role in giving stool its brown color so when a patient tells Kumar Desai, MD, gastroenterologist, hepatologist, and pancreaticobiliary specialist in Thousand Oaks, California ...
After the meconium, the first stool expelled, a newborn's feces contains only bile, which gives it a yellow-green color. Breast feeding babies expel soft, pale yellowish, and not quite malodorous matter; but once the baby begins to eat, and the body starts expelling bilirubin from dead red blood cells, its matter acquires the familiar brown ...

Urobilin is the chemical primarily responsible for the yellow color of urine. It is a linear tetrapyrrole compound that, along with the related colorless compound urobilinogen , are degradation products of the cyclic tetrapyrrole heme .
