A member asked:

Why are stools brown but when you wipe it's yellow?

A doctor has provided 1 answer

Bile pigment: Stool contains, among other things, a substance called bile which is produced by the gall bladder. Bile helps digest dietary fat. When a thin layer of stool is spread across toilet tissue, the greenish yellow color of bile is more readily visible than it is when it's in, well, a scoop of poop.
