Well, apparently not "everybody" knew you were talking about the brighter one. If I had to guess, I would have thought the one with its head in the pic. But as you said, I know now.
I found the link, but since it talks about the "white noses and washed out heads" and the snake you are asking about doesn't have its head in the pic, I'm not sure how much it is going to help.

I did not find a "yellowbellyballs.com" but yellowbellyball.com is Amir's site. I have not done business with him but he has a good reputation and I would trust that a snake he is selling is what he says it is. If you are asking because you didn't ask him when you saw it, consider the possibility that it is a yellowbelly combo, because Amir works with YBs a lot.
