It could be, although since the month code is for October it might have been made for the folllowing year's Spring line or even as a Resort color. There aren't any light greens listed as fall or winter 1996 colors.
Below are catalog shots of each color but of course the colors might not be completely accurate, and it also dependes on whether yours has faded over the years - if it has there should still be a few small areas that have close to the original color, maybe the trim around the inside zipper pocket.
Here are the Wheat (the darker tan shade), Maize and Sea colors from Spring 1996, and the Aqua, Lime and White from Spring 1997. Hope this helps a bit and doesn't just confuse things even more.
