Some advice? - Juvenile Jag colouration

[Cam]

Hello all. I've not owned a carpet before, but after quite a bit of reading the species does seem more or less ideal as the kind of pet I'm interested in.

So henry at A1Pythons has some babies from his beautiful "Day Glow Jag" female for sale. My question is about the likelihood that their colour will change to the nice yellow of their mother with time (right now as youngsters they are quite grey). I know this species tends to colour up as they mature but I am not sure how well you can predict the colour of a juvie based on it's pedigree.

FWIW I'm interested in it as a nice looking pet snake, and not for the jag gene and breeding or anything (though I won't rule that out).
