  • The Colour Strike was an industrial action by technicians at all ITV companies from 13 November 1970 to 8 February 1971 who, due to a pay dispute with their management, refused to work with colour television equipment. At that time ITV had recently switched to colour transmissions, requiring the individual companies to invest heavily in new equipment. Early colour television studio cameras consisted of four tubes to relay the picture: three were receptive to colour with the fourth providing a high-resolution monochrome image which was still required as many viewers still watched on monochrome receivers. The final colour picture was created by combining the chrominance and luminance signals, but the technicians simply switched off the colour tubes whilst this dispute took place. This meant that even though colour equipment was available, all shows were recorded and broadcast in monochrome, thus denying the ITV companies the ability to sell airtime at the higher value that colour transmissions dictated.
