Hoping someone could help unscramble this for us.

We are receiving a female spider ball python next week and were looking at different combos to pair her with.

We wanted to know what the difference is between a pastel cinnamon and a pewter. Isn't a pewter a pastel x a cinnamon? How isn't a pastel cinny a pewter then?

If we purchased a cinnamon pastel and bred him to our spider, would the outcome possibly produce pewter bees for us? OR would we need a Pewter x spider to make pewter bees?

Thanks in advance
