I was doing some thinking (thats a scary thought!) about the blue tint of the LM windows and remembered an image that shows the blur tint of the window while the LM is on the moon. The image is AS12-46-6726. The window has the surface of the moon reflected in it and it is a very blue tint. The best image to view this is at GRIN. I think there is just a blue tint to the window. Perhaps it is an artifact from some coatings on the window(?) or prehaps its just the nature of the window material.
