After the 1952 Olympics, Colò linked his name to a line of ski clothing and, according to the regulations of the time, he was considered a professional. In 1954, he was disqualified by the Italian Winter Sports Federation (FISI) and was not allowed to participate in subsequent races, notably the 1954 World Championships in Åre, and he retired at age 33. The ban was lifted 35 years later in 1989.
