All my Whites have clear gems, too, but I think I remember reading somewhere on the Forums a few were made, or might have been made, with pale-yellow ones.
The worst of it is, I *did* see a Red Fire in person — two of them, actually — at Worldcon! I just couldn’t remember them well, because I was too busy being amazed by the two Golds on the table with them! 🙂
My white scratcher, mama & Emp all have clear white crystals…longing to see a RF in person as well…
