I know how to sex my ball pythons, just I only have 2 males and when i pop their hemi out, both of them its dark colored.

I hatched my first baby (normal yay! lol), and I tired to sex it, now it looks like a hemi popping out but its white, not dark colored like my other males. but it doesn't seem like so much pops out of my females, but my females are just all white inside of there.

so my question is are all hemi's dark colored?
