Hard to tell by pics on Pinside and IPDB because of possible fading but I’m guessing a pretty medium standard Blue would be close.
If your needing it so you can repaint the cabinet you might get lucky like I did on my Night Rider. I could tell that the orange/red had faded on the cabinet but under where the lockbar is the Orange/red color was intact as I imagine it was from the factory or close to it, so I was able to get a nice match from that area.
