Correct Engine Color

I am not familiar with 68 small blocks, but I believe there is definitely a controversy about color. Red, turquoise, or orange.
I think it probably depends on time of year of assembly, and which assembly plant.
I'm pretty sure Mopar used four different shades of orange.
1. Race hemi, on max wedges and pre-street hemi hemi's. Very yellow orange.
2. Early street hemi orange 66/68? Hemis only (I think) pretty straight-up orange
3. Street hemi orange 69 up 340, 440, hemi reddish orange. (NOT much different from chevby orange
4. Fram orange, used on air cleaners to match a Fram element.
This is what I've found, and I think is correct. I may be full of ship.
