Lozenge camouflage  Lozenge camouflage was a military camouflage scheme in the form of patterned cloth or painted designs used by some aircraft of the Central Powers in the last two years of , primarily those of the Imperial German "Luftstreitkräfte". It takes its name from the repeated polygon shapes incorporated in the designs, many of which resembled lozenges. In Germany it was called "Buntfarbenaufdruck" (multi-colored print) but this designation includes other camouflage designs such as "Splittermuster" and "Leibermuster", and does not include hand-painted camouflage. During the early stages of the Great War, the Germans were looking for a way to effectively camouflage the aircraft of the "Luftstreitkräfte" to inhibit enemy observation of the aircraft while it was airborne and when on the ground. Large, irregular blotches with two or three colors were used on the upper surfaces of the wing which led to the development of the "Buntfarbenanstrich", the lozenge camouflage made up of repeating patterns of irregularly shaped four-, five- or six-sided polygons. Because painting such a pattern was very time consuming, and the paint added considerably to the weight of the aircraft, the patterns were printed on fabric, and the fabric was then used to cover the aircraft. This printed fabric was used in various forms and colors from late 1916 until the end of the war. Lozenge camouflage appeared primarily on German aircraft along the Western Front but some air units of the Austro-Hungarian Imperial and Royal Aviation Troops used the pattern on the Eastern Front and on the Italian Front. Lozenge camouflage came in varying widths, sometimes in 4.5-foot-wide (1.4 m) bolts of fabric, and pieces were cut to fit between the leading and trailing edges of the wing. Fabric sections laid chordwise were lined up next to each other so that the pattern repeated itself regularly across the wing, except for the ailerons which were covered in fabric laid sparwise, perpendicular to the wing pattern. Some aircraft had the fabric applied diagonally. As a part of field repairs, regularly laid fabric patterns from the factory might be overlaid with the same pattern but at a different angle, or with fabric from a different camouflage design. Later in the war, some patterns were applied more quickly with fabric laid sparwise along the full wingspan. Hasty factory work began to resemble the rushed field repairs.
