Sorry in advance for not being able to resolve this on my own.

 

What color is Color Number 4 on a 48 Plymouth Build Card?

 

Where is this information found?

 

Thanks!!!

I wonder if that number relates to a paint chip color card put out by Chrysler Corp.. If you know the original color of your car, you can see if those two match.  Just a guess.

Found one card said 4 is Airwing grey
