Awesome! What you pair the pastel with will also have a huge impact--choose light colored CLEAN animals to breed to your pastel, for better color in the hatchlings.
Pay attention to lineage there, as well. A token light animal from an otherwise dark line won't necessarily give good results.
Never accept 'just a normal' as an answer when you ask what a pastel's parent looked like--normals matter just as much as morphs. In fact, when shopping for a base morph, I would rather one of the parents were a normal--you can see a lot more of what's going to be in the genes when one parent is normal. Morph colors and characteristics can mask that, often. Good photos of the normal parent are important.
