Rapid Transit: Bright green stool can be caused by many things but most of the time is due to the rapid movement of stool through the colon. The color of stool changes from green (bile) to yellow-brown as it passes through the colon. Any factor which leads to an increase passage of stools through the colon can prevent the change of coloring, hence the green stool. Ex: diarrhea after taking antibiotics.

Not much.: Stool starts out green in the small bowel, and bacteria turn it brown. Rapid transit of stool through the intestines, or a change in bacterial populations, can prevent this from occurring.

Stool Color: Stool color is generally influenced by what you eat as well as by the amount of bile (a yellow-green fluid that digests fats) in your stool. As bile pigments travel through your gastrointestinal tract, they are chemically altered by enzymes which changes the pigments from green to brown.Food may be moving through the large intestine too quickly(diarrhea).So bile doesn't have time to break down.

In short, stool can be different colors depending on what you eat. All colors are normal except white and tar black. If either of those two colors appear you should seek out medical attention as soon as you can.
