I should know this, but I don't. Is there any other factory side window tint other than green?

No other color. Rear windows were never tinted. I never could figure that one out due to the angle of the window and all the reflections that you get from inside the car.

The clear sure looks like it has a slight tint. But the only available tint is green.
Scotty has a post on the difference including pics.
