His answer was actually correct in terms of color, at least for HG/SS. The Trainer Card colors change pretty much every game.
His answer was written with more info than MSBU's, then MSBU edited his ansswer.
Read the edit info, look at the times. Then look at the bulbapedia link.
I might be defensive too if people were telling me I was wrong when I was in fact with correct information. And when I answered with more info first. Everybody who downvoted this answer please remove your downvote. I also gave this best answer, for a variety of reasons.
Artist KS, I apologize for the behavior exhibited here. I hope it will not happen again, to you or to any other user.
