For those that are taking the OP's age into consideration.. Tiff has been here long enough for most of the veterans to know that she is extremely mature for her age. She speaks in a way that would convince anyone who didnt know any better that she was 30 years old. She generally gives good advice, doesn't get mad when people critisize, and has wisdom beyond her years..
That said.. IMO that doesnt look like a pastel at all. Maybe the picture is bad quality but it looks like a normal all the way to me. Going to look at it would be the only way to know for sure. Just dont get over your head with snakes. It doesnt take much to reach the point where you are overwhelmed and will feel bad if you decide you must sell a snake or 2 to make things more managable.
You know that its up to you. You have seen all the CL postings on here. Many poeple have adopted snakes from CL. It can be a great thing or a bad thing. Quarantine should be longer than usual but in the end the decision to buy is up to you.
