Why does a patient having hepatic jaundice would pass clay colored stools when his urine is dark colored and his body produces urobilinogen?

Bilirubin: Bilirubin is a yellow breakdown of hemoglobin from old red blood cells. It is cleared normally from the body by the liver and is passed in the bile to help digest fats; it gives stool a brown color. When the liver can't clear bilirubin, it builds up in the body and the skin turns yellow (jaundiced). Elevated levels are excreted in the urine (urobilinogen=brown urine) while stool turns clay color.
