The first Ki-84s came out of the factory in natural metal finish, with only the red national markings and a black anti-glare panel painted on. Many of these later received field-applied solid or mottled upper camouflage schemes. This was most likely done in whatever shade of green was available, but it could also have been brown or some combination of green and brown. In late 1944 the IJAAF mandated that the factories apply a scheme to all newly-produced aircraft of khaki brown upper and light grey lower surfaces. This was most likely to prevent brand new NMF aircraft being easily seen on the ground by marauding American aircraft.
The B&W photo of this aircraft shows a very dark colour was used, darker than the late war factory brown. There is no known shade of Japanese brown paint that dark so I went with dark green for my skin. As for the paint wear the photo shows some missing paint on the wing root which I duplicated, but very little on the fuselage. Some of my other Ki-84 skins have a lot more paint chipping, I just go by whatever the photo shows.
