The Africa Korps used many different styles of uniform ranging from a sandy colour shorts and short sleeve shirts to full combat uniforms similar to those worn in Europe. The difference between the European combat uniform and the one worn in Africa was the colour, the Africa uniform was usually what the Germans called olive green although in reality it looks more like a Khaki colour, helmets were usually painted a sand colour. Occasionally the fieldgrey uniforms were used.
The fiqure below highlights one type of uniform worn by the Africa Corps, it was painted using Vallejo Acrylics, they have a large range of paints and are of a high quality. Humbrol enamels are also good.
Hopes this helps.
