I think that you ay be onto something here. I thought for the longest time that "The Fly" was primer. Then I was looking at a picture I snapped of it and saw that it was silver. I actually didn't believe my camera and had to get a closer look the next time we were in the same place. We painted a '40 Ford a color that was called Ghost Grey (gray?) when I was in high school. it was so pale that it looked white to me unless it was parked near a white car. Of course you have to allow that you are hearing this from a man that gets confused a little bit by some colors.
