In brief: Color

What color do you expect it to be? Normally, it is dark because of the presence of bilirubin biproduct, stercobilin.
I'd be concerned if it were "light", it then may signify a problem with your bile excretion. On the other hand, if it is liquid and black it may signal bleeding from your gastrointestinal tract that needs to be promptly evaluated.
