The colour of the PSNI uniform is bottle green. Pre-1970s RUC uniforms retained a dark green called rifle green, which was often mistaken as black. A lighter shade of green was introduced following the Hunt reforms of the early 1970s, although Hunt recommended that British blue should be introduced. The Patten report, however, recommended the retention of the green uniform (Recommendation No. 154). The RUC officially described this as 'rifle green'. When the six new versions of the PSNI uniform were introduced, in March 2002, the term 'bottle green' was used for basically the same colour to convey a less militaristic theme.
