Well, there is an NFPA color standard, IIRC, based on the flow rate of the
largest diameter fitting on the hydrant. This is slightly different than
the size of the main it is hooked to as a five-inch connection is going to
flow more than a three-inch connection on the same sized main.

As I understand it, Boston MA USA paints hydrants to distinguish the
primary hydrant mains, the High Pressure System (pumps activated by Fire
Alarm Office on request), and private hydrants located on a large property.

Boston colors do not match adjacent mural aid communities' hydrant colors,
which might be NFPA, I don't know.
