Mouth rot or pigment??

So, I noticed that around Kaa's mouth looks a little bit discolored. However, I don't know if his mouth is actually discolored or if I'm just noticing that his mouth is that color. I'm just worried, it really shouldn't be mouth rot all of his temps are all spot on.

Here's a picture:

What do you guys think??

I really don't see anything abnormal. If you are truly concerned about it I would recommend a wellness visit at your closest exotic vet.

looks fine to me. I wouldnt worry about it.
