By the 1970s, all locomotives had received all over British Rail blue with a full yellow nose; by 1975 most locomotives had also received their TOPS numbers. Their livery remained the same until the early 1980s when 'Large Logo blue' was introduced. This entailed the yellow nose continuing round to behind the driver's door and up to the top of the windscreen and a full height 'double arrow' logo. These locomotives had the top of the nose painted black to lower the risk of the driver being dazzled by the sun. Freight-allocated examples received a similar livery - the only difference being the blue was replaced by freight grey. In 1987, the Sectors were launched, incorporating a new livery of 'three tone grey'; a light grey lower bodyside, medium grey cantrail and a dark grey roof, along with a bright Sector logo (Coal, Metals, Petroleum, Distribution, General and Construction). In addition a metal double arrow logo was fitted. This livery co-existed with plain blue, large logo blue/grey and the new InterCity and Regional Railways liveries right up to the end of British Rail in 1996.
