I don't know about the green; I presume the aluratek is about the same as the jetbook.
The jetbook looked rather greyish, perhaps somewhat brown, depending in what kind of environment you look at it.
I do know that a greenish tint is the byproduct of LCD crystals that are not 100% aligned, much like a brown/black-ish tint is the byproduct of the polarization filter.
So it could be the byproduct of regular (cheaper) LCD technology.
The back could be reflector, but I presume it's more possible for it to be metallic in nature.
