In 1940 the general staff of the Kriegsmarine (navy) produced a much more detailed plan accompanied by a map showing a proposed German colonial empire delineated in blue (the traditional color used in German cartography to indicate the German sphere of influence as opposed to the red or pink that represented the British Empire) in sub-Saharan Africa, extending from the Atlantic Ocean to the Indian Ocean.[50] The proposed domain was supposed to fulfill the long-sought territorial German goal of Mittelafrika, and even further beyond.
