Very interesting. Is it possible that the the het Cinder influence is what makes the 2nd one so light?.. I've seen Butter's range from very pale to very deep yellow, but the p/h Cinder looks almost like a snow it's so light..Whatever is causing the differences in appearance, they both look awesome (congrats).
When I picked out my Butter Motley, there were quite a few others to choose from in his clutch. One of them had a perfect motley/hurricane pattern too, and I was so tempted to get him. But I went with the one with the most noticeable yellow coloration, in the hopes that he would just get more richly colored as he aged. And he's developed into quite a deep yellow guy over the years.
It would be neat, though, to see a Butter Motley as light as yours. Really shows how varying a snake of the same morph can be, just based on the line it was bred from, the het influences, or just the natural range in appearance from one individual to another.
