I did a 66 Barracuda about 10 years ago in that color. It's not as yellow in real life as the picture you posted. Can't remember if it was Omaha orange or Orange Crush. One is lighter than the other. I used the late model Chrysler color. Like I said I can't remember which one.
Looked up the paint codes. Omaha is P62 (Chrysler) Crush is PL4 (Chrysler). Go to a Jobber and look at the chips.
Thinking about it, I think this was Crush which is PL4. Crush is the yellower of the two.
Here is a pic of the car so you can get an idea of the color. Outside it was more yellow and less red.
