PAINTING AND APPLYING DECALS Basic colours are: dark green (top and sides of the fuselage, upper surface of the main wings and horizontal stabilizer); light greyish blue (lower surface); and orange yellow-identification colour (half- nearer to the fuselage-of the main wing front edges). Towards the end of the war, some planes had dark green painting called "special attack painting" and some had no overall painting with silver duralumin exposed except on the top of the nose which was painted black for prevention of reflexion. (The black paint was also applied to the nose top of some planes with green painting.) It was a general rule that Japanese planes in oversea territories should have a narrow white line called the border breakthrough line or field identification mark. Planes belonging to interception forces in Japan proper had a national insignia on a white line or square so that ground unites could distinguish them from enemy planes. The inside of the fuselage and the wheel cover wells were painted in transparent blue preserv- atives (some say these were dark opaque bluish grey) directly on duralumin material. See colour drawing. Basic Painting Flat black for prevention of reflexion applied to silver planes with no Sun-disc with a rim overall painting.
