I'm sure it's a great looking snake, but everything is yellow not just the snake. As Paul said, the white balance is off and perhaps it was a yellow flash that was reflecting off of a banana.
From the name I would assume it'd be a beautiful snake, but those pictures are so poor. Ya think if you were selling an $8,000 snake you'd get better pictures...
My pastel champagne seems to get more yellow every shed. It was really cool as a hatchling and then went through an ugly stage. It's now over a year old and is starting to look really cool. I'm not savy enough to post pictures here but I can post them in the gallery. That picture on KS is yellow but I had lots of trouble when trying to photograph my male.
It does look like one, although some pieds end up with that crazy awesome pattern where colours tend to be one colour, it coule be that. I always loved that. Either way hawt pied.
