Hataka HTK-A701 Blue Grey (RAL 7031) is a high-quality acrylic model paint from the Red Line series by the renowned Hataka Hobby brand, designed primarily for airbrush application. This particular shade of blue grey (RAL 7031) is widely used as a base color in historical modeling—especially for replicating military vehicles and aircraft of many European countries, particularly Germany, during the Cold War and modern times.

The RAL 7031 shade precisely matches the color used in NATO camouflage, as well as the painting of Bundeswehr equipment – the German armed forces. It is ideal for projects such as Leopard 1 and Leopard 2 tank models, Marder armored vehicles, as well as for recreating German military trucks and aviation (e.g., Tornado aircraft) from the 1970s up to the present day. For this reason, Hataka HTK-A701 is used primarily in armor and aviation modeling.
