When mine are doing the shed thing, from blue to complete shed, they are pretty reclusive except to eat.
That said, all of mine are fairly reclusive most of the day given that they are nocturnal!! In the evening and in the early morning they are all active, but the opaque ones remain hidden.
Your snake is perfect and doing exactly what it ought to do!! When mine are in blue, and until they shed, I bump my humidity to about 72% because I live in a very dry high desert. If I left my humidity at 50% the shed would be a disaster (as I found out with the very first shed one time). Bumping it up gives my snakes perfect sheds 100% of the time.
