Original color? or primer?

I took off my door panels and it looks like a dark green, forest green? This is a 1969 911T and its red. Is this green primer or something like that sprayed on before the finishing coat was applied? I can't find green on anything else, just the inside of the doors.

I've seen a bright yellow primer used on cars (European style, I think) but am unfamiliar with green as a primer. Maybe someone else knows... Are both doors like that?

Have you checked your paint code??

Both doors are like that, even inside part of it is sprayed green. I'll check the paint code once i find my vin number
