      The brown colour of faeces comes from the bile and bilirubin which are formed when hemoglobin (oxygen binding protein) in red blood cells breaks down.

      Faeces can be different colours as well – it often depends on what you’re eating, particularly if you eat a lot of red or purple coloured things.
