Answers:

It's brown because it is primarily a mixture of bile, mucus and retired red blood cells. Bile/muscus are greenish and the dead blood cells are rusty red. Green and red make brown. The reason what you eat usually doesn't effect the colour is because the chemicals that give food a colored appearance are relatively simple for your digestive system to break down and absorb, so it loses its 'colour' before it even leaves the small intestine.

its all in what you eat.

Mix a whole bunch of different colors, and you get brown. Same as with paint. Unless you have a lot of one thing with a dominating color (spinach) you'll end up with a brownish mixture. It also works with paint.

generally, its brown cause we eat a lot of crap! but, actually, it is brown because of the juices secreted by the body. They are called bile juices (bilirubin and bilivirdin), secreted by the Bile Duct. They help the body digest the food. They give the color to the excreta of the human body and also the stink! ;)

What does it matter? Most people just wipe their a-- and walk off and leave it !..Eat a bunch of polk salad or spinich and it should turn green ! Eat a lot of different flavors of jello and all this together and it should look like a Christmas tree !..if you are really worried about it !
