The ITV Colour Strike was one of the more unusual union disputes faced by the ITV group of companies in the 1960s and 1970s. Starting on Saturday 15th November 1969, the ITV companies had started to transmit a full colour service although due to the high costs involved in the conversion of studios and transmitters, the roll out of colour television had, by November 1970, not been across the entire country with viewers in the regions covered by Westward Television, Border Television, Grampian Television and Channel Television still watching ITV in black and white.
