IJN D1 Dark Green

IJN D1 Dark Green: the Imperial Navy's upper-surface green

IJN D1 Dark Green is the Imperial Japanese Navy's dark green for aircraft upper surfaces, combined with J3 grey undersides as the standard pattern by 1944. It is the defining colour of mid- and late-war Navy aircraft in factory finish. Use it for A6M5 and A6M2-N Zero, N1K1-J and N1K2-J Shiden, J2M Raiden, G4M Betty, B5N Kate, D4Y Judy and many other Navy kits. It chips readily over aluminium, so a hairspray or salt technique pays off. Water-based and formulated for the airbrush, it covers in few coats with a smooth matte finish.

The problem with matte finishes

A matte finish hides nothing: fingerprints, uneven coats and gloss patches all show. Spray light, even coats, avoid handling the parts, and finish with a matte or satin clear to keep the sheen consistent.

How to apply

1. Shake the bottle for at least 60 seconds.
2. Prime with a grey primer and let it dry fully.
3. Airbrush straight from the bottle, no thinning needed. Use a 0.2–0.4 mm nozzle at around 20 PSI (1.4 bar) and apply light, cross-hatched coats, letting each one flash off before the next.
4. Let the paint cure overnight before masking, decals or weathering.
5. Seal with a water-based clear: matte or satin to keep the military finish, gloss under decals.
6. Clean the airbrush with water before the paint dries.

Why modelers choose Koloi Aqua

• Ready to spray: no guessing thinning ratios, the same result from every bottle
• Cleans up with water, so there are no strong solvent fumes at the bench
• Fine pigment grind for 1:8 to 1:72 scales, so panel lines and detail stay crisp
• One system: primer, colour and clear designed to work together

Shelf life

Estimated shelf life of more than 12 months when stored tightly closed between +10 °C and +28 °C, away from frost and direct sunlight. Shake well before use; if the paint has thickened or separated and does not remix, do not use it.
