Mystery Snail Color Change?

[SansyFrance]

Hello all,

I'm a bit confused today. When I went to check on all my fish this morning when I woke up, I noticed my black mystery snail has begun to turn a more tan or yellow color around the edges of his shell and moving up. I did a littler research to see if this could be bad, but got mixed findings, with some saying its natural and good, and some saying its bad.
Does anyone know anything about this??

I've had tons of mystery snails of all different colors. Never saw any color change in any of them. I'm wondering if it's new she'll growth. It's usually lighter around the edges as it comes in I think
