What colors are my truck?

[84 400]

Almost finished with the metal repair on the cab of my 1977 K10.

The truck was black from the factory with a redish color interior. The SPID in the glove box was long gone when I got it. The PO had it painted some ”70’s green” in the early 80’s. His thought was that it would make the truck ugly so no one would steal it. Well I painted it old aemy green to hold me over and now want to repaint it back to a 70’s green.

What color does it look like to you??

GM 517
GM 568
GM 41

How about the interior??


I want to keep the inside black and red and put the outside back to a similar green to what he had.

Here are some old pictures:

Thanks for any help
