Not your average Mohawk

Caption said this is an OV-1B, 2nd ASTA Sqn. Korea, 1960s. Anybody have more info on the story behind it. Also, and mostly, colors? Looks like FS 34087 base with black. Any thoughts on the light green? Any better photos of the pattern?

Not related ,but… Didnt know the Mohawk had IFR capabilities.

This poster suggests it’s a color shift in the photo as possible grey.
