Hey guys, I got this working and now understand all there is to it, including this way and the old way of doing things (thanks Yossam!)
But I have one last problem
I cant get my noise (PF) small enough to fit on the leaves. I m using the old way of doing thing right now; applying a PF to the color function of the internal shader)
So what I want is my new brown color to not change every leaf totally brown, but to happen blotches and such. As I said I made the noise the way I want it, but it is to big.
here is the PF:

Again, I am trying to make the noise small enough so that it fits on a leaf, where some of the orgnial green color remains, in other words, not totally altered every where.
Scale lead in and such. I can seem to get it smaller.
THis node is based off of one of Inky's.
