TAMXF14 - Tamiya - Flat IJA Gray Acrylic - 10mL Bottle

Tamiya XF-14 Flat IJA Gray represents the Imperial Japanese Army Air Force standard grey-green finish — Hairyokushoku (灰緑色, "ash green colour"), designated #1 in the Army Aircraft Material Standards, KôKaku 39. It is a cool, muted grey-green, lighter and less saturated than the IJN grey-greens, and served as the factory-applied overall finish on IJAAF aircraft from the late 1930s through the early Pacific War before camouflage upper surfaces became standard. From 1942–43 onward it persisted as the lower-surface and undersurface colour on aircraft receiving dark green upper camouflage, and continued in use on fabric-covered control surfaces across most IJAAF types through to 1945. It is worth noting that despite sharing the name Hairyokushoku with IJN colour standards, the Army #1 and Navy M-series colours are distinctly different shades — they should not be used interchangeably. For the grey-green base of natural metal IJAAF aircraft or early-war overall schemes, XF-14 is Tamiya's designated choice; modellers seeking a more precisely researched match for specific aircraft are directed to Mr. Color C128 as an alternative cited by leading researchers.

Tamiya Acrylic paints are a hybrid acrylic formula built on water-soluble resin — they can be thinned with water, isopropyl alcohol, or lacquer thinner, and clean up easily with water before curing. When thinned with Tamiya Lacquer Thinner, the paint lays down faster, dries harder, and bonds more aggressively to the substrate. The hybrid resin chemistry means the paint film remains slightly soluble after initial drying — subsequent brush strokes can reactivate and lift the layer below if applied without restraint. For this reason, airbrushing is strongly recommended for large surface coverage. Brush painting is workable for detail and touch-up work, but requires a gentle, deliberate stroke and a fully cured base layer. See our Tamiya Acrylic vs. Enamel vs. Lacquer guide for a full breakdown of paint type differences.

• Nakajima Ki-27 Nate — overall Hairyokushoku factory finish on the fixed-undercarriage fighter that was the IJAAF's primary front-line type at the outbreak of the Pacific War, operating from bases in Manchuria against Soviet forces at the Battles of Khalkhin Gol (1939) and over China, Malaya, and the Philippines in December 1941 with the 1st, 11th, and 77th Sentai
• Nakajima Ki-43 Hayabusa (Oscar) — grey-green lower surfaces and early overall finish; factory-applied Hairyokushoku on Ki-43-I and early Ki-43-II airframes operating from Malaya and Burma with the 59th and 64th Sentai in the opening campaigns of December 1941 through mid-1942, before dark green upper camouflage became standard
• Nakajima Ki-44 Shoki (Tojo) — overall grey-green on early production Ki-44-I and Ki-44-II airframes; the Ki-44 was one of the first IJAAF types specifically designed as a high-altitude interceptor, entering service with the 47th Independent Chutai at Saigon in 1942 and later defending the Home Islands from B-29 raids with the 47th and 70th Sentai, 1944–45
• Kawasaki Ki-45 Toryu (Nick) — lower-surface Hairyokushoku on the twin-engine heavy fighter; Kawasaki-built aircraft are specifically documented as using an overall grey-green close to FS 16350 in the early war period before dark green upper camouflage was applied, with the 4th and 13th Sentai operating in Burma and the 53rd Sentai in night-fighter Home Island air defence, 1944–45
• Kawasaki Ki-48 Lily — overall and lower-surface grey-green on the twin-engine light bomber operating over China, Burma, and the Dutch East Indies with the 8th, 45th, and 208th Sentai, 1941–43; lower surface colour retained after dark green upper camouflage was applied from 1942
• Mitsubishi Ki-46 Dinah — lower and side surface Hairyokushoku on the high-speed strategic reconnaissance aircraft; early production Ki-46-II airframes operated in overall grey-green before receiving dark green upper camouflage, covering routes over Malaya, Burma, Australia, and India with the 8th and 18th Independent Chutai, 1941–43
• Fabric control surface dope — XF-14 applicable as the grey-green doped finish on fabric-covered elevators, rudders, and ailerons across virtually all IJAAF aircraft types through to 1945, where fabric surfaces were finished separately from adjacent metal panels and took on a slightly lighter appearance with weathering
• Lower surface base coat — standard application under XF-13 dark green upper surface schemes across the majority of IJAAF subjects from 1942 onward; the two colours together represent the core two-tone scheme for Ki-43, Ki-44, Ki-45, Ki-48, Ki-61, and Ki-84 kits
