Pewter Whiteside

[Chilali]

hey everyone. I'm excessively new to the specific names that are given to morphs of corns, but is a pewter with pale sides a pewter 'white side', or just a normal pewter?

The reason I ask is because a pet store in town has a snake for sale labeled as a Pewter White side. Its a gorgeous snake with excessively pale sides that make it so that only the faintest bits of actual darker markings are visible along its back. (I wasn't able to get a picture because they watch closely when you go near the glass cases.)

I have checked pictures here and have seen snakes similar to the one in the store, but everyone just calls theirs a Pewter.

Forgive a newb here, but why the extra name? I'm guessing its partially a way to be able to charge $239.99 for the snake.

I'm a right? Or is there actually a Pewter Whiteside morph? I have no idea! Thanks for any response.
