Banana with something else going on?

I bought this banana female from a local pet shop (I rescued it) they said she was a banana but I believe there's something else going on with her, she has a pretty paint job but don't have as much yellow as all the "pure" bananas I have seen, more purple and grey, help would be appreciated, just getting into the banana game:)https://ball-pythons.net/forums/webk...5f99/imagejpeghttps://ball-pythons.net/forums/webk...5175/imagejpeg

Banana CG are VERY variable so without a picture no one can tell you.
