Looks like a pastel champ to me. These type of posts always help if you include more info. Who did you buy it from, where did you see the snake for sale, did he say he produced it, did you ask about the sire and dam? Champs hide other genes very well so there could be 6 genes present for all we know, but since the seller said pastel then that is what I would go with.

Craigslist add.... He bought it from a repticon show last month. She is only 700 grams so she hasn't produced yet. He knew nothing of the sire and dam.
