Brown: The color of stool is most commonly various shades of brown due to a combination of several factors (bile content, transit time, diet, medications, intestinal flora/bacteria). These factors may result in green or even a yellow hue.

Stool color: The stool changes colors regularly depending on diet and other factors. The only time the stool color is abnormal is if it is black or red, which can indicate active bleeding and occasionally when it is very pale in color, when it can represent blockage of the bile duct. Any other color is just a variant of normal. Hope that helps.

Black stool: If the stool is solid black or maroon, especially if it is very foul smelling, it may represent what is called melena, which is usually a sign of bleeding from the digestive tract. The bleeding is often active and this is a medical emergency. If you experience this, you should go to the emergency room immediately. Good luck.
