This is going to be the wrong thing to notice but I got invested enough to actually read the pages more than look at the images and was wondering if anyone could tell me what the Pokeballs in the bottom right of the "Trainer tips" section represent.
I thought it was just decorative, but the colors are different in some images and I can't tell what they mean since they don't seem to be based on threat or evolution level (i.e. Pidgey has a copper one while other forms have silver ones so it'd make sense if it's a power thing, but Ninetails doesn't have gold while Wigglytuff does.
