Greetings everybody! I have a question for those more experienced in morphs than am I.

A bit over a year ago I bought a baby ball python who was listed as a normal male (sold for $10). My girlfriend noted that he looked more yellow compared to her full grown normal. I didn't think much of it until I got a good look at her ball python in some daylight and realized that yeah, his brown coloring was rather yellow in comparison.

After talking to some people, it's been suggested he might be a pastel but I'm still not certain. Here's some pictures of him at various ages (not all in chronological order).

When I first got him


Dealing with a stuck shed, at about 6 months old


Actually got him to look at the camera without investigating it (almost a year old)


Here's a pic where you can see his belly (~10 m/o)
