Below; a selection of images of early Bf 110 Nachtjäger in the overall black finish. A special article for modellers.
Up until around 1943 all night-fighters were painted black - 'black' was generally considered to be a 'non-reflective colour' and indeed special non-reflective pigments were used. However these resulted in increased drag. In addition 'black' aircraft were vulnerable to observation from above, especially when silhouetted against clouds illuminated from the ground - indeed this was one of the the prime factors behind the establishment of the wilde Sau being trialed at the time of the Hamburg raids of July 1943.
