question about baby snake getting "blue"

well when i got my baby bp he was about as big as round as a penny. well since I have had him "about a month and a half" he is bigger around than a quarter, my question is his skin is turning blue, but his eyes are clear and his stomach is white not salmon pink. i was wondering what is the first sign of a shed?

If his markings a getting hazy "blue"bump his humidity up because he is going to shed!

Every BP displays different signs at different times. I have a pastel that I can tell is going into shed nearly 2 weeks before she goes blue, while my mojave male recently shed without me even realizing that he was in shed.

Generally speaking once you see a BP's eyes/pattern go blue it is time to boost the humidity to 70%-80% until the BP sheds.

I noticed about 3 weeks ago his tail end was turning a bluish color, then tonight when i handled him, his whole body was the same way kinda bluish dull color but his stomache isnt pink and his eyes arent hazy, but im sure he is getting ready to shed because he has to be 3 times the size from when i got him from the petstore, thanks for the replies
