Ah. Well, Shadow characters aren't always a thing in persona, 3 didn't use them.
I'm late on this but you're partially right.
Shadow characters have been in every Persona game, including 3. However their role and function are not always the same. When I say you're partially right, the base game for 3 didn't really have any, but The Answer did have a Shadow, but the circumstances revolving them was unique to say the least.
Also P6's main color theme should be purple.
No reason I just want to see them use purple... I mean I would say pink but pink has technically already been used, and I hate them reusing color schemes.
