COLOURBLIND® was developed in 1991 when Geoff Cox was asked to design and deliver the first week of an induction training programme for Air Traffic Control cadets. The young people involved came from a range of backgrounds: direct from school or university, from business and industry, from air traffic control in the Armed Forces. Each had to face an intensive, demanding training programme in which team communication would be fundamental to success.

Each, ultimately, would accept professional responsibilities which allow absolutely no margin for error, misunderstanding or ambiguity. The exercise allowed for active exploration and rehearsal of these vital interpersonal communication skills. Since 1991 COLOURBLIND® has been used worldwide across languages, cultures and business backgrounds, to focus on the fundamental skills of great twoway communication and the achievement of shared meaning. It is also used to explore team problem-solving, team understanding of abstract concepts and to explore team culture.
