...and a good one, at that.
Everyone's right; the difference between a regular amel motley and a sun motley is not only lack of white (since 99% of ALL amel motlies lack obvious white), but the deeply-saturated colors, like your's. I originally named Sunglow Motlies back in the mid-90s when we discovered these clean, saturated colors with almost no stippling of white (or other colors) in the ground and marking color zones. Therefore, the visual difference between sun motlies and amel motlies is subjective, but usually distinct. What makes your snake amel and motley are genetic mutations, but what distinguishes between sun motley and amel motley are the results of polygenetics (as stated elsewhere in this thread). In this case, quantative interactions between genes (not mutations).
I'm no prognosticator, and do not seek attention in that realm, but your's has visual markers for being het caramel. I recommend you breed it to snake with genes for butter motley.
