1980 Paint Code Question

[JurassicJeep24]

Just a quick question about paint codes. I have a 1980 J10, from what I can tell the original paint was a metallic brown, but the paint code on the VIN tag is showing 9BOH. I know 9B is Olympic White and the OH is Navy Blue, does that mean it was originally a two tone paint?
