why did my ball change color?

[Peter Williams]

how would she be gravid when she claims that she is the only ball python she owns? We have all heard of some morphs getting brighter with age, but since she got it from petsmart it leads me to believe that it was originaly a pastel that got sold as a normal since it appeared to be so. I say she is a pastel from those pics, or my eyes are playing tricks on me. I am not the only one, I say pastel

Here you go. Take a look at this too.
