I did some research on this myself. Even started a thread some years ago about how to duplicate that greenish color. After a lot of fooling around, I have come to believe that that greenish tint is due to age and heat. Just my opinion...
I compared fresh Duplicolor 1616 to a hidden area on an original paint 1966 389 harmonic balancer and the colors were pretty much dead-on as far as I could tell.
To reinforce that, I recently pulled my water-pump off that was painted 8 or 9 years ago and guess what? It was greenish tinted compared to the freshly painted water-pump I was replacing it with.
Can't find the water pump pic but what's pictured below is what convinced me that there is just not a lot of difference in the original paint and Duplicolor 1616
