Help! polaroid type 59 very GREEN

I've been experementing with some expired polaroid type 59.
The first exposure was done indoors with incadescent light. The colors did not have alot of saturation but they were fairly accurate, with a slight orange tint due to the tungsten bulbs but it looks like it procesed correctly.

Further exposures taken outdoors turned out extremely green!
According to the polaroid documentation, overdeveloped negs will turn green.
However according to the type 59 specs.. it is more sensitive to green when underexposed. So ive tried it underexposed and overexposed, underdeveloped and overdeveloped, and nothing seems to restore the balance.

So what am i missing? Why are all the exposures so green? It looks like there is no red at all.

Of course, you may be having problems with old film color shifts, however it is a known fact that some Polaroid color films shift to green with exposures longer than 1/10 sec. So, if you are making "longish" exposures outdoors, I would expect a green shift.

Well, the slowest my graflex does is 1/30th of a sec. I tried exposures of 1/125th and 1/60th and its still green. But then maybee that was underexposing.. which leads to green also.

Is there such thing as a minus-green filter?
