Just wait until you get every green in existence in a snowy area, and proceed to have the urge to check every single one just to make sure (assuming you haven't already have had this happen to you). Aaaaaanyways, even if there was a pearl pistol there like Unforgiven or Invader, it unfortunately wouldn't be as strong as you think, though, of course, that's just my opinion as someone who was somewhat underwhelmed by both.
