Help Identifying millipede

[insect Art]

I've recently purchased 2 "green millipedes" and would like help identifying them. All the pet store I bought them from could tell me was that the will get 4-5 inches long, and turn more green as they grow.
I don't know how to put pictures up here, so anyone wishing to help can go to my web site at www.entomologydesign.com and click on "Our Pets"
Their pictures are the second ones down.
I just want to be sure I am caring for them correctly.
Thanks!

Can't tell you what they are, but if the colors are true in the pic, I don't think they will ever turn green. They look to me like some I had. They stayed peach and gray their whole life.
