Why is my poop magenta?

So i just came out from droppin a bomb in the pot, and before i flushed (i always do this) i like to take a little glance at what i leave behind. normally its just like a deep choclate colored log with little cracks and bumps on it, but today it was a magenta purple pink color and i screamed and ran out without flushing so now my house smells like s because its still just sittin in there chillin. what do i do?
