Is this color okay?

[Tiberius]

I've never seen seen my Jackson with this color on him before. Normally, he's only green and black. I noticed the spot of color after I finished holding him.
It's a little hard to tell from the pictures but it's kind of a bluish grey color. Is this normal?



Thanks in advance.

Looks like sheeding but also looks like burnt? Don't take my answer right away, wait for more experience keeper.

It has not gotten any better since my last post. It is now usually a black or dark grey color now.
I guess a burn could be possible but I have the highest temperature at 85°F... But he can get a little closer to the light than the gauge is at...
