Chestnut coloration in Northern Pines...

Hello,

I own an 8 month old female Northern Pine and her coloration is showing varying degrees of chestnut to almost pink.

Along her sides she is showing a lighter chestnut, almost a pink coloration and there is some darker chestnut along her dorsal scales. I saw it when I got it and with this last shed it has become more defined.

Is this a normal coloriation trait or??? I read on a caresheet that sometimes this color does come out as the snake gets older.

Would beinterested in hearing thoughts etc...

Thanks
Charles
