The new flagship locomotive of the German Federal Railroad was to shine not only with its technology, but also with its appearance. Consequently, the color design of the prestigious class 10 became quite an important issue. The participating locomotive builders submitted their drafts and color studies for a decision in the meeting of the factory committee on the August 4, 1955. In addition to color selection, particular attention was directed to design of the decorative striping and the smoke deflectors. The study, designated TLO 54801, from Krauss Maffei showed a very dynamic and innovative looking locomotive in a red color scheme. The extremely large tear-drop shaped smoke deflectors with diagonal front line accent the forward thrust of the machine. However, in the following meeting on December 14, 1955, the committee was not able to decide on this design.
