Good : Good news! the only stool colors we get really concerned about are red (blood from colon), black (blood from small intestine or stomach), or white (liver is not working well). Colors such as brown, yellow, orange, green, even blue (blue kool-aid or blueberries) or purple (beets) can all be normal and usually associated with diet. If you have a persistent change in your stool habits, you should contact your physician since this could be a sign of an underlying disorder, but a one-time strange stool that is not red, black or white is usually of no concern.

Green stool: If stool is loose, the reason for green stool could be rapid gut transit time. Green cabbage, lettuce, peas, cabbage, spinach, broccoli, green salad, green leaves, celery and green beans as well as food that contains green food coloring can lead to green stool. Some medications can change stool color.
