Meaning of Stone Colors

I've been reading the FAQ and I want to check if I have this correct. Tan stones are from the gallbladder and green stones are from the liver. This means if I am getting mostly tan stones and only a couple of green ones each time that I am still working on cleaning out the gallbladder. When I start to get more green ones then I will have cleaned out the gallbladder and moved on to the liver. Does this sound right?
