Not really a matter of the manga, but I think it's still better to post here to avoid spoiling anime-only viewers over in the anime review blogs.

As most of you probably know the anime gave Silver's ice a purplish cast. I wonder if Gray's Ice will change colour to purple or something in between purple and his current while/blue once Silver gives him Devil Slayer Magic.

I doubt he'll switch back and forth between the two colours depending on whether he uses Ice-Make or IDSM, though that'd be the coolest option.
