What colour...

I don't know which forum to post this question on and thought this one was as good as any! I have sort of an embarassing question. I'm wondering what colour "healthy" stools are supposed to be? I've come across conflicting information. I've heard some people say that they should actually be tan in colour, but I've also read that tan is unhealthy. Also, what should the consistency be? I've read that it should break apart when the toilet flushes, but I've also read that this suggests diarrhea....i am very very confused...
