Quick question about traits vs card color.

Really Just curious: We know that the colors of cards and decks dictate certain playstyles. Ie: purple makes use of the trash and so on.

Do traits also mean this card has a certain playstyle, or are they just for aesthetic purposes.

And I'm not really referring to the fact that certain cards refer to these traits like, " If you have a card with the X trait, do this". What am saying is more like "do insectoid digimon have some perk or ability specific to them?"

I hope this makes sense.
