fire ball question?

[briz]

i a wondering if anyone can tell me how to distinguish a fire ball python from a normal?
when breed to other morphs it appears to be easy but as a base morph i'm finding it hard to figure out (since i have not seen to many in person.)

I had posted this before but here is the pic again. Fires really are not that hard to pick out, especially in a clutch. which ones are the fires in the pic?
