The color comes mainly from bilirubin, a pigment that arises from the breakdown of red blood cells in the liver and bone marrow. The actual metabolic pathway of bilirubin and its byproducts in the body is very complicated, so we will simply say that a lot of it ends up in the intestine, where it is further modified by bacterial action. But the color itself comes from iron. Iron in hemoglobin in red blood cells gives blood its red color, and iron in the waste product bilirubin gives rise to its brown color.
Although other colors of poop are possible, red, green, yellow, white, etc

it isn't always. eating a random mix gets processed to a brown state. all the various colors get mixed together. eat a lot of lettuce and little else and it will be green. (trust me, i did it once).

Because of the billiary pigments excreted by the liver. These pigments give also the yellow color of the urine.

It's a mix of all the colors of the food you ate! There's probably more to it than that, but that's all I could think of.
