The Thing - Anybody else notice this? Flaw in the transfer?

[GGX]

There is a scene in The Thing at exactly the 36 minute mark (and slightly before) where Blair is talking to Clark about being with the dogs. If you notice, the scene's color scheme fluctuates. It goes from the normal look to a darker, almost greenish tint. It only lasts about a second but it's almost like everythign fades in and out.

I originally thought it was because of different camera lenses or film stock being used when the film was created. But it happens right in the middle of the conversation. Right when the camera is zoomed close onto the actor's faces. It really bugs me.

I would just like to know if this is a problem with the Blu-ray transfer or due to the source. Anybody have the standard DVD version of The Thing to compare?
