What is the belly like? Is this an adoption from someone who has no idea what it is and no info on parents? Or something you picked up a long time ago from something like Petco that labeled it as "Fancy Ball Python" or something like that?
My best guess is Enchi Firefly without any other info. The face pattern, reduced "eyes" in side pattern, and overall cleanliness of pattern all point towards Enchi. Pastel I'm iffy on because there is low blushing and not a strong pattern indication for, but with the right other genes pattern can be pushed back towards normal again, and low blushing isn't unheard of on pastel. Color is way too bright to be Pastel alone, so definitely something has to be helping it. While OD is a good guess because of cleanliness of pattern, I just don't see it color wise or in the head stamp. Fire I'm guessing because of the brightness, as it's one of the few lightening morphs that really hold true past early juvenile. DG would be one of my best guesses if it weren't such an expensive and rare morph right now; I feel like if you had one you would know it.
