Welcome, to Fauna, Kyle!
Some very nice snakes you have there.
There are no het Pastels nor het Super Pastels. A Pastel (or Super Pastel) is either a genetic/phenotype Pastel (or Super Pastel) or it is not.
Pastel is what is known as Co-dom in the Ball world.
One Pastel gene gives you a Pastel phenotype.
Two Pastel genes gives you an enhanced Pastel phenotype (aka Super Pastel).
Edit: Technically, you could say that a Pastel is het Pastel (since it carries only one Pastel gene lol) but, with just one Pastel gene, it gives you the Pastel phenotype. So, it is not referred to as het Pastel.
