That is my favorite color for the 65 cars. I restored a 65 ss chevelle years ago,and the color code (L) was definitely more blue than green. I would say it was more of a teal than anything,but could look more green as the sun went down. The code was the same on the 67 line but I do not know if the color was exactly the same. It seemed to be a lot more common on 67 gto's than other cars.
