Originally, the school colours were those of the school badge – bottle green, grey, and red – with the addition of black. The bottle-green blazers were highly distinctive but were later replaced by more traditional black ones. In the 1970s, the school uniform stipulated that other items had to be in "the school colours", which allowed pupils of both sexes to dress entirely (shirt, jumper, and trousers) in bottle-green or bright red if they so wished. Later, the uniform was changed to stipulate black or grey for trousers, although there was some leeway for "self-coloured" shirts and jumpers.
