Bundeswehr M47

Thinking of doing a what if diorama with a Bundeswehr M47, what would be the proper colors for this tank in the late 50s early 60s? I looked at a few pics online and some show a green which I’m assume is NATO green and others kind of show a grey. Thank you!

I believe you are looking for “Gelboliv” (Yellow Olive) RAL 6014. I know Vallejo makes it in both ModelColor and ModelAir flavours, not sure about other brands.
