<bot>: THANK YOU FOR YOUR QUERY. Color and stool size varies just like frequency of bowel movements, but there are a few warning signs. A stool color other than brown, tan, yellow or green, any shade of these are normal. Causes:Almost always due to food coloring or food additives. Stool color relates more to what is eaten than to any disease. Sometimes in child Chat Doctor.  Stools often come out the same color as the Kool-Aid or Jell-O that went in. The only colors we worry about are red, black (not dark green) and white. While normal stools are typically light to dark brown. Bile: Most dark green stools are caused by bile. Green stools are more common with diarrhea (rapid transit time), but also seen with formed stools. Foods: green Jell-O, grape-flavored Mediate (turns bright green), green fruit snacks, spinach or other leafy vegetables. Dark green stools (e.g., after eating spinach) may look black under poor lighting. Medicines: iron (e.g., in formula)HOPE THAT HELPS.
