BS 1710 - The British Way of Marking Pipes

BS 1710 stands for British Standard 1710. This is a framework legislated in 1984 that specifies how pipelines, ducting and electrical conduits should be labelled. The labels and tapes provide a visual identifier to warn of the risks and dangers of the release of pipeline contents and to prevent accidents and injuries from any such release.
BASIC IDENTIFICATION COLOURS
BS 1710 gives specific guidelines on the colours of pipeline labelling. Pipelines may be labelled with multiple colours in specific patterns, or they may be labelled with a single colour know as the 'basic identification colour'.
Although there are dozens of different categories of pipeline contents, there are distinct categories of conduits that share the same basic identification colour:
