Hi! From what I can see, if I were to hypothesize I'd say your little one is either a blizzard or a murphy's patternless. I'd be more confident that it was a blizzard of some kind.
They're very beautiful! You definitely got lucky with a cute little charcoal-looking gecko!
If you have any questions about morphs, feel free to visit the Rydikulus Reptiles Facebook page! Our "Files" tab has a lot of valuable information on leopard gecko care and husbandry that is well organized and easy to understand!
We also post daily about different leopard gecko morphs, so maybe you'll come across a morph that best matches your baby's as well!
Don't hesitate to shoot me a DM if you have any other questions. Have a great day!
