Bilirubin, a pigment derived from the breakdown of hemoglobin in red blood cells, is responsible for the typical brown coloration of feces. As bile is metabolized by bacteria in the large intestine, it is converted to urobilinogen, which is further oxidized to stercobilin, the pigment that ultimately gives feces its characteristic color.
