I agree. I think the very yellowish/orange tint in most of the photos there is very likely from incandescent bulb from just above beaming directly down on the snake though. Here is one of the photos that show the upper portion of the snake to be much grayer colored that is away from the direct lighting.

I think it's probably a clean, typical looking Gray Ratsnake (P.spiloites).
