Where two (2) colors do not have sufficient contrast to easily
differentiate between them, a six (6) inch band of a contrasting color
should be painted on one (1) pipe at approximately thirty (30) inch
intervals. The name of the liquid or gas and arrows indicating direction
of flow should be painted on the pipe.
